LHCb discovers matter-antimatter asymmetry in charm quarks

With 99.9999 percent statistical certainty, LHCb scientists have observed a difference between the decays of matter and antimatter particles containing charm quarks. The idea that matter and antimatter particles behave slightly differently is not new and has been observed previously in studies of particles containing strange quarks and bottom quarks. The huge amount of data generated since the start of LHC Run 2 combined with the introduction of more advanced methods to tag the particles of interest enabled scientists to collect enough matter and antimatter D0 particles to finally see these decay differences beyond a shadow of a doubt.
