With this discovery, there were now two complete generations of particles: the first—the electron and the up and down quarks; the second—the short-lived muon, charm, and strange quarks. A 40-year-old debate about charm quarks in protons may have been settled by a new machine-learning analysis of data from the Large Hadron Collider (LHC) at CERN and other facilities. However, not all particle physicists agree with this assessment. For decades, physicists have debated whether protons contain what are known as intrinsic charm quarks.Over the years, many pro sports mascots have come and gone.

An exception to this are decays of ground state charmonium mesons, which decay via annihilation of the charm and anti-charm quarks. Thus, open charm particles are the only ones allowing the study of weak decays of an up-type quark in a bound state.

This is because the transformation proceeds by the exchange of charged W bosons, which must change the charge by one unit. The general pattern is that the quarks will decay to the most massive quark ... Subatomic particle - Quarks, Hadrons, Leptons: The discovery of the pion in 1947 seemed to restore order to the study of particle physics, but this order did not last long.
