The Large Hadron Collider Beauty (LHCb) project has observed an exotic particle made up of four charm quarks for the first time.
The LHCb collaboration has observed a type of four-quark particle never seen before. The discovery, presented at a recent seminar at CERN and described in a paper published today is likely to be the first of a previously undiscovered class of particles never before seen by physicists.
The finding will help physicists better understand quarks, a type of elementary particle which is a fundamental building block of all matter. Quarks form together to form composite particles known as hadrons, which include protons and neutrons. This breakthrough new discovery can help scientists now understand the complex ways in which quarks bind themselves together to form these composite.

The LHCb team found the new tetraquark using the particle-hunting technique of looking for an excess of collision events, known as a "bump", over a smooth background of events. Sifting through the full LHCb datasets from the first and second runs of the Large Hadron Collider, which took place from 2009 to 2013 and from 2015 to 2018 respectively, the researchers detected a bump in the mass distribution of particles, which consist of a charm quark and a charm antiquark.
The bump has a statistical significance of more than five standard deviations, the usual threshold for claiming the discovery of a new particle, and it corresponds to a mass at which particles composed of four charm quarks are predicted to exist.

They should be putting that money and talent into finding a good, cost-effective treatment for viruses. Nothing they're doing is relevant to anyone's life.

1) LHC and CERN have been around since way before the "virus"
2) They are physicists and nothing to do with the medical field .
3) Depends on what one calls "relevant" .
4) Do you absolutely know for sure that it is not relevant to anyone's life ?
5) The funding was already in place. You did know the LHC and CERN is not a US endeavor , right ?
Denying ignorance .
Why ?
Some folks need to learn

Cern: "We need 21 billion to make an even bigger collider, how we gonna sell that to the fools, i mean donors. Lets tell them we've discovered a new particle."
Donors: "21 billion? That could feed a lot of people for a lot of years. Thats a lot of schools we could build"
Cern: "Did we mention its an exotic particle?"
Donors: "Is 21 billion enough???!!!"
