“We observe in our data clear signs of a new particle, at the level of 5 sigma, in the mass region around 126 GeV. The outstanding performance of the LHC and ATLAS and the huge efforts of many people have brought us to this exciting stage,” said ATLAS experiment spokesperson Fabiola Gianotti, “but a little more time is needed to prepare these results for publication.”
"The results are preliminary but the 5 sigma signal at around 125 GeV we’re seeing is dramatic. This is indeed a new particle. We know it must be a boson and it’s the heaviest boson ever found,” said CMS experiment spokesperson Joe Incandela. “The implications are very significant and it is precisely for this reason that we must be extremely diligent in all of our studies and cross-checks."

Wonder if it will ultimately help explain the enigma of dark matter and dark energy.
 
Congratulations CERN LHC.

A tremendous technical achievement, congratulations to all who have worked on this for the past 50 years or so.

Let us hope technologies tumble out of this discovery in the same way that they did from discovering and understanding the electron... I have to say I'm skeptical about this hope, however if it does happen many many strange and magical things could be within reach.

I'm 38 right now I hope to see some of this in my lifetime. :-\

"This is the first time [a dark matter filament] has been convincingly detected from its gravitational lensing effect," said astronomer Jörg Dietrich of the University Observatory Munich, in Germany. "It's a resounding confirmation of the standard theory of structure formation of the universe. And it's a confirmation people didn't think was possible at this point."

:D :) ;) :p ...


cheers,

It's an interesting observation, but we're no closer to knowing what dark matter is.
 
 
With regard as to the LHC's planned successor:
Experimental physics rarely tops the news agenda, but the 2008 launch of the Large Hadron Collider (LHC) catapulted academic theories such as the search for the Higgs boson – also known as the “God Particle” – into the spotlight.

Now, the European Organization for Nuclear Research (CERN) is planning for a successor of the LHC.

The new circular supercollider will sit next to its predecessor at CERN in Switzerland, but will be nearly three times its size, with a circumference of 100 kilometers. The Future Circular Collider (FCC) will pick up from the LHC to continue studying the smallest particles in the world.

Contributing to this revival of particle accelerators, the U.S. is getting its first new collider facility in decades, set to start operating around 2030. One of the missions of the Electro-Ion Collider (EIC) in New York will be to make particle acceleration more energy-efficient.

This should also impact the use of accelerators outside experimental physics. As successful as the LHC has been – eventually finding the Higgs boson in 2012 – particle accelerators come in many shapes and sizes. And they are used in a wide range of areas from radiation therapy for cancer to treating wastewater and cleaning flue gases from power plants.

As an aside, I find it interesting that Mitsubishi Heavy Industries paid for this article.
 
Large Hadron Collider restarts

Beams of protons are again circulating around the collider’s 27-kilometre ring, marking the end of a multiple-year hiatus for upgrade work

22 APRIL, 2022

The world’s largest and most powerful particle accelerator has restarted after a break of more than three years for maintenance, consolidation and upgrade work. Today, 22 April, at 12:16 CEST, two beams of protons circulated in opposite directions around the Large Hadron Collider’s 27-kilometre ring at their injection energy of 450 billion electronvolts (450 GeV).

“These beams circulated at injection energy and contained a relatively small number of protons. High-intensity, high-energy collisions are a couple of months away,” says the Head of CERN’s Beams department, Rhodri Jones. “But first beams represent the successful restart of the accelerator after all the hard work of the long shutdown.”

“The machines and facilities underwent major upgrades during the second long shutdown of CERN’s accelerator complex,” says CERN’s Director for Accelerators and Technology, Mike Lamont. “The LHC itself has undergone an extensive consolidation programme and will now operate at an even higher energy and, thanks to major improvements in the injector complex, it will deliver significantly more data to the upgraded LHC experiments.”

Pilot beams circulated in the LHC for a brief period in October 2021. However, the beams that circulated today mark not only the end of the second long shutdown for the LHC but also the beginning of preparations for four years of physics-data taking, which is expected to start this summer.

Until then, LHC experts will work around the clock to progressively recommission the machine and safely ramp up the energy and intensity of the beams before delivering collisions to the experiments at a record energy of 13.6 trillion electronvolts (13.6 TeV).

This third run of the LHC, called Run 3, will see the machine’s experiments collecting data from collisions not only at a record energy but also in unparalleled numbers. The ATLAS and CMS experiments can each expect to receive more collisions during this physics run than in the two previous physics runs combined, while LHCb, which underwent a complete revamp during the shutdown, can hope to see its collision count increase by a factor of three. Meanwhile, ALICE, a specialised detector for studying heavy-ion collisions, can expect a fifty times increase in the total number of recorded ion collisions, thanks to the recent completion of a major upgrade.

The unprecedented number of collisions will allow international teams of physicists at CERN and across the world to study the Higgs boson in great detail and put the Standard Model of particle physics and its various extensions to the most stringent tests yet.

Other things to look forward to in Run 3 include the operation of two new experiments, FASER and SND@LHC, designed to look for physics beyond the Standard Model; special proton–helium collisions to measure how often the antimatter counterparts of protons are produced in these collisions; and collisions involving oxygen ions that will improve physicists’ knowledge of cosmic-ray physics and the quark–gluon plasma, a state of matter that existed shortly after the Big Bang.

I just wish SSC were finished. Large Hadron was a consolation prize.
