European atom-smashers ponder response to Russia's invasion

The Geneva-area research center that houses the world's largest atom smasher is grappling with ways to punish Russia's government while protecting Russian researchers who work to help solve the deepest mysteries of the universe.

Could massive gravitons be viable dark matter candidates?

Today, many research teams worldwide are trying to detect dark matter, an invisible substance that is believed to account for most of the matter in the universe. As does not reflect or emit light, its presence has been indirectly ...

Homing in on the Higgs boson interaction with the charm quark

Since the discovery of the Higgs boson a decade ago, the ATLAS and CMS collaborations at the Large Hadron Collider (LHC) have been hard at work trying to unlock the secrets of this special particle. In particular, the collaborations ...

First detection of exotic 'X' particles in quark-gluon plasma

In the first millionths of a second after the Big Bang, the universe was a roiling, trillion-degree plasma of quarks and gluons—elementary particles that briefly glommed together in countless combinations before cooling ...

New insight into the internal structure of the proton

While the Large Hadron Collider (LHC) at CERN is well known for smashing protons together, it is actually the quarks and gluons inside the protons—collectively known as partons—that are really interacting. Thus, in order ...
