The Large Hadron Collider is ready to once again start delivering proton collisions to experiments, this time at an unprecedented energy of 13.6 TeV, marking the start of the accelerator’s third run of data taking for physics
A new period of data taking begins on Tuesday, 5 July for the experiments at the world’s most powerful particle accelerator, the Large Hadron Collider (LHC), after more than three years of upgrade and maintenance work. Beams have already been circulating in CERN’s accelerator complex since April, with the LHC machine and its injectors being recommissioned to operate with new higher-intensity beams and increased energy. Now, the LHC operators are ready to announce “stable beams”, the condition allowing the experiments to switch on all their subsystems and begin taking the data that will be used for physics analysis. The LHC will run around the clock for close to four years at a record energy of 13.6 trillion electronvolts (TeV), providing greater precision and discovery potential than ever before.
“We will be focusing the proton beams at the interaction points to less than 10 micron beam size, to increase the collision rate. Compared to Run 1, in which the Higgs was discovered with 12 inverse femtobarns, now in Run 3 we will be delivering 280 inverse femtobarns1. This is a significant increase, paving the way for new discoveries,” says Director for Accelerators and Technology Mike Lamont.
The four big LHC experiments have performed major upgrades to their data readout and selection systems, with new detector systems and computing infrastructure. The changes will allow them to collect significantly larger data samples, with data of higher quality than in previous runs. The ATLAS and CMS detectors expect to record more collisions during Run 3 than in the two previous runs combined. The LHCb experiment underwent a complete revamp and looks to increase its data taking rate by a factor of ten, while ALICE is aiming at a staggering fifty-fold increase in the number of recorded collisions.
With the increased data samples and higher collision energy, Run 3 will further expand the already very diverse LHC physics programme. Scientists at the experiments will probe the nature of the Higgs boson with unprecedented precision and in new channels. They may observe previously inaccessible processes, and will be able to improve the measurement precision of numerous known processes addressing fundamental questions, such as the origin of the matter–antimatter asymmetry in the universe. Scientists will study the properties of matter under extreme temperature and density, and will also be searching for candidates for dark matter and for other new phenomena, either through direct searches or – indirectly – through precise measurements of properties of known particles.
“We’re looking forward to measurements of the Higgs boson decay to second-generation particles such as muons. This would be an entirely new result in the Higgs boson saga, confirming for the first time that second-generation particles also get mass through the Higgs mechanism,” says CERN theorist Michelangelo Mangano.
“We will measure the strengths of the Higgs boson interactions with matter and force particles to unprecedented precision, and we will further our searches for Higgs boson decays to dark matter particles as well as searches for additional Higgs bosons,” says Andreas Hoecker, spokesperson of the ATLAS collaboration. “It is not at all clear whether the Higgs mechanism realised in nature is the minimal one featuring only a single Higgs particle.”
A closely watched topic will be the studies of a class of rare processes in which an unexpected difference (lepton flavour asymmetry) between electrons and their cousin particles, muons, was studied by the LHCb experiment in the data from previous LHC runs. “Data acquired during Run 3 with our brand new detector will allow us to improve the precision by a factor of two and to confirm or exclude possible deviations from lepton flavour universality,” says Chris Parkes, spokesperson of the LHCb collaboration. Theories explaining the anomalies observed by LHCb typically also predict new effects in different processes. These will be the target of specific studies performed by ATLAS and CMS. “This complementary approach is essential; if we’re able to confirm new effects in this way it will be a major discovery in particle physics,” says Luca Malgeri, spokesperson of the CMS collaboration.
The heavy-ion collision programme will allow the investigation of quark–gluon plasma (QGP) – a state of matter that existed in the first 10 microseconds after the Big Bang – with unprecedented accuracy. “We expect to be moving from a phase where we observed many interesting properties of the quark–gluon plasma to a phase in which we precisely quantify those properties and connect them to the dynamics of its constituents,” says Luciano Musa, spokesperson of the ALICE collaboration. In addition to the main lead–lead runs, a short period with oxygen collisions will be included for the first time, with the goal of exploring the emergence of QGP-like effects in small colliding systems.
The smallest experiments at the LHC – TOTEM, LHCf, MoEDAL, with its entirely new subdetector MAPP, and the recently installed FASER and SND@LHC – are also poised to explore phenomena within and beyond the Standard Model, from magnetic monopoles to neutrinos and cosmic rays.
A new physics season is starting, with a broad and promising scientific programme in store. The launch of LHC Run 3 will be streamed live on CERN’s social media channels and high-quality Eurovision satellite link starting at 4.00 p.m. (CEST) on 5 July. Live commentary from the CERN Control Centre, available in five languages (English, French, German, Italian and Spanish), will walk the viewers through the operation stages that take proton beams from injection into the LHC to collisions for physics at the four interaction points where the experiments are located. A live Q&A session with experts from the accelerators and experiments will conclude the live stream.

1 An inverse femtobarn is a measure of the number of collisions or the amount of data collected. One inverse femtobarn corresponds to approximately 100 trillion (100 x 1012) proton–proton collisions.

Bad idea…still the possibility of a black hole…
Didn’t see Your post. no matter. Totally agree.
O’rly? Explain in detail using proper equations how a black hole (which aren’t even proven to exist) is going to manifest.
At this point, if the rotunda suddenly blew of the Capitol building and ten million demons burst though a newly created black hole to hell, darkening the DC skies, would anyone be surprised ? It be just another day in Clown World From Hell for me.
Some professional physicists think that’s possible, if very unlikely…As an amateur, I think a 1/1000000 chance is far too high for basically worthless research….
And in the end, they will still be no closer to understanding the divine nature of everything in the universe.
Yes
And just where is greta?
“The launch of LHC Run 3 will be streamed live on CERN’s social media channels and high-quality Eurovision satellite link starting at 4.00 p.m. (CEST) on 5 July.”
‘Bout 3 pm there…any inhabitants of a distant star system may note the formation of a Black Hole?
So all countries support this while at ‘war’.
So I e heard the amount of energy used to do this is humongous but ‘we’ have an energy shortage.
I think the whole program is possibly just a money capture like NASA.
The energy shortage narrative takes a hit….
Russia makes massive oil discovery in the Arctic
Russian energy company Rosneft announced the discovery of a massive oil resource in the Pechora Sea with an estimated 82 million tons of oil.
A drilling campaign in the Medynsko-Varandeysky area led to the discovery of the field. “During the tests, a free flow of oil was obtained with a maximum flow rate of 220 cubic meters a day,” the company’s statement read on Wednesday, noting that the “oil is light, low-sulfur, low viscosity.”

Very interesting!
I wonder how many millions of dinosaurs and how many millions of years it took to make 82 MILLION TONS OF OIL …. and in the fucken Arctic of all places.
More and more with each passing year I am doubting the entire THEORY that oil is biological. Not kidding, either.
Abiotic
I think you nailed it.
Many years ago we had a poster here named “PhD in Geology”. He posted for about two months and said exactly that.
And guess what? The poor feller got HAMMERED BY EVERBODY …. as typical here with unpopular opinions, he was called all kinds of names. Terrible names. Especially by Admin. The guy just couldn’t take it and left abruptly.
Not making this up!!
So, we’ve come along way, baby!! No one has called you a dumb fucken retard with an IQ lower than whale shit. In fact, “abiotic” seems to be the popular opinion now! We’re getting woke!
I think his PhD was in masturbation.
Yup. He wrote a book about it … which I bought, purely for research purposes.
I thought you were the study subject.
Have you retired from getting in the ring and occasionally pounding the shit out of your visitors?
Just remember that George Forman dusted off the gloves and had a triumphant return as a fat old guy!!!
(On second thought, you could be anyone here. Who would know but you? Just as long as you’re not STUCKY!!!)
It’s rare when I feel the need to kick someone in the balls. They really need to touch a nerve to get me fired up.
I don’t dopplegang as someone else.
Admirable.
No, but you are known to dox those that do just when things get interesting.
Mine too….never trust a fart, and never waste a hard on
Hasn’t always been the arctic. Nothing has looked like this forever.
Bacteria can now digest cellulose so no more new oil
Gut bacteria is how termites have always digested cellulose.
Yep. Abiotic. Saying crude oil comes from dinosaurs is just a f’n stupid as claiming Diamonds come from Dinosaurs. Another reason they want to destroy Russia.
“The government of the Soviet Union initiated a “Manhattan Project” type program, which was given the highest priority to study every aspect of petroleum, to determine its origins and how petroleum reserves are generated, and to ascertain what might be the most effective strategies for petroleum exploration.”
And the Earth has virtually unlimited oil and diamonds…

“Where does Oil really come from? Is it a “fossil fuel” as you have been led to believe? No! Absolutely not! Everything you have been taught and preached and sold by the establishment is a 100% fictitious lie!”
Have a look. The Emperor Has No Clothes.
Dude in the video looks like the fella who blew up that giant gyroscope thingamabob in Jodie Foster’s movie Contact.
I can’t watch anyone who shakes his fucking bangs out of his eyes every ten seconds like Sarah Palin.
And I can’t listen to anyone who calls earth ‘Gaia’.
!!!
Not that you asked.
The theory probably has merit though.
t’weren’t dinosaurs! t’were codfish livers
Its plausible, oil came from dinosaur shit and the gas came from dinosaur farts. Totally reasonable. 1000 dinosaurs = 1 barrel of oil. Do the maff yourself.
Energy for an experiment, but not for the commoners…
How many in Europe will starve, freeze, of die of heat issues over the next few years because of all the power this is wasting?
A lot of well educated intelligent people embarking on research financed by the people of the world while receiving absolutely nothing in return . Any discoveries that benefit the world will come at another huge expense to adapt and use with any measure of practical use .
Then there is the discovery of poof nothing Or THE BIG BANG blowing a hole thru the planet rocking it of its axis as we are all spun off into oblivion !
Yes I know probably not likely ranking right up there with safe & effective mRNA vaccines , that horror story is still playing out !
SHIT these WEF elitist are even fartheads are instigating war to play cover up .
Can you imagine what they can do with this nonsense if we survive
Non-toll-booth energy needed.
Ummm..mmmmm…..Uh…. I think I’m gonna need a translation. What exactly are they doing? Crashing particles with enough electricity to power all of Europe? No wonder there’s an energy crisis. Seriously, I think what they are doing is on the border of other dimensions. When particles reach a certain level of smallness they become super positioned in Quantum physics existing in 2 or more places at the same time if my grasp of the concept is correct. Crazy shit.
I think you just described the Rapture.
So when these particles collide, while eating your sandwich, hitting that golf ball, walking the dog, sitting on the toilet, or watching the sun set, and suddenly explode at least you’ll have a reasonable explanation as to why.
Large Hardon Collider?
Don’t ask, don’t tell, I guess.
MEGA Smart analyst, Gail the actuary posts some new wisdom on interest rates and energy BIG issues..
I remember reading about peak oil back in 2005. Got to say I’m not afraid of oil running out anytime soon.
There’s always an Arquillian Battle Cruiser, or a Corillian Death Ray, or an intergalactic plague or a looming financial crisis that is about to wipe out all life on this miserable little planet, and the only way these people can get on with their shitty lives is that they do not know about it!
Where are they getting the energy for this? Coal powered plants, nuclear?? Greta could have a field day!
Likely has its own nuclear reactor…while they shut down others and build windmills.
I think that discussion is way over my head.
Thanks to watching the Big Bang Theory on TV, I at least recognize most of the terminology, while not understanding much of what was written.
Will this provide any joy, food, peace, security, contentment, hope, love, mercy, kindness, honor, integrity???
*****SCIENCE****FUCK YEAH****
That infernal Bottomless Pit isn’t going to open itself, Doc.
SOMEBODY has to do it!!!
meh… this type of experiment is a brilliant example of the receeding horizon, where ‘just a little more’ is never actually enough.
Giant meteor? Hold my beer..
But, will this solve the problem of condoms clogging my septic system?
It’s turtles, all the way down.
This started the day they ran two trains at each other. The rationale is the same. “People will pay to watch the wreck…”
