In March 2024, the CMS collaboration announced the observation of two photons creating two tau leptons in proton–proton collisions. It is the first time that this process has been seen in ...

For the first time, by studying quantum correlations between triplets of secondary particles created during high-energy collisions in the LHC accelerator, it has been possible to observe their ...

The CMS collaboration at CERN have searched for evidence of long-lived particles beyond the Standard Model in proton-proton collision events Despite the huge success of the Standard Model of particle ...

The universe looks like it is mostly empty space. Remove the stars, planets, dust, and gas, and what remains is nothing at all. Physics tells a stranger story. The vacuum is not truly empty. It is ...

Inside each proton or neutron there are three quarks bound by gluons. Until now, it has often been assumed that two of them form a "stable" pair known as a diquark. It seems, however, that it's the ...

In proton–proton collisions, the CMS Collaboration measures the simultaneous production of three particles, each consisting of a charm quark and a charm antiquark, which yields insights into how the ...
