At a seminar today at CERN, the LHCb collaboration presented a new analysis of data from a specific transformation, or “decay,” that a particle called B0 meson can undergo. The analysis is based on twice as many B0 decays as previous LHCb analyses, which had disclosed some tension with the Standard Model of particle physics. The tension is still present in the new analysis, but more data are needed to identify its nature.
