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 ...

New exotic matter particle, a tetraquark, discovered

Today, the LHCb experiment at CERN is presenting a new discovery at the European Physical Society Conference on High Energy Physics (EPS-HEP). The new particle discovered by LHCb, labeled as Tcc+, is a tetraquark—an exotic ...

ATLAS experiment searches for 'charming' decay of the Higgs boson

Key to understanding the Higgs boson and its role in the Standard Model is understanding how it interacts with matter particles, i.e. quarks and leptons. There are three generations of matter particles, varying in mass from ...

Observation of four-charm-quark structure

The strong interaction is one of the fundamental forces of nature, which binds quarks into hadrons such as the proton and the neutron, the building blocks of atoms. According to the quark model, hadrons can be formed by two ...

Physicists reveal why matter dominates universe

Physicists in the College of Arts and Sciences at Syracuse University have confirmed that matter and antimatter decay differently for elementary particles containing charmed quarks.
