Recent observations from experiments worldwide have reported anomalies in the decays of a bottom quark to a charm quark, a charged lepton (electron, muon, or tau), and the corresponding neutrino. These observations hint at possible deviations…
The CMS Collaboration probes decays of the Z boson which would defy our expectations of lepton behavior
How strict are Nature's conservation laws governing the interactions among elementary particles? Physicists once assumed, based on experience…
CMS sees evidence of the Upsilon meson decaying into two tau leptons for the first time at a hadron collider
Beyond our best current understanding of particle physics, encapsulated in the standard model, various theoretical models predict the…
