A team of researchers with The NNPDF Collaboration has found new evidence to support the theory of "intrinsic" charm quarks. In their paper published in the journal Nature, the group describes how they used a machine learning ...
Over the course of the 20th century, physicists have discovered numerous elementary particles. The largest family of these particles are the so-called hadrons, subatomic particles that take part in strong interactions.
The international LHCb collaboration at the Large Hadron Collider (LHC) has observed three never-before-seen particles: a new kind of pentaquark and the first-ever pair of tetraquarks, which includes a new type of tetraquark. ...
