The LHCb collaboration at CERN in Geneva has observed and measured a crucial oscillation in the measured mass of neutral charm mesons arising from the particles changing into their antiparticles and back again. Although the detection is fully consistent with the Standard Model of particle physics, it could provide a “very clean” window into physics beyond the Standard Model in future experiments, the researchers say.
