Description
We report resent flavor physics results, using pp collision data collected by the CMS experiment at the LHC, including the observation of two excited Bc states, the study of the B->J/Psi Lambda p decay, and a search for charged lepton flavor violating decays tau->3mu. The first analysis is based on an event sample corresponding to a luminosity of 143 fb^-1 at sqrt(s)=13 TeV. The Bc excited states are observed in the Bc pipi invariant mass spectrum, with the ground state reconstructed through its decay to J/Psi pi. The second analysis uses a data set of 19.6 fb^-1 collected at sqrt(s)=8 TeV. The BR of this decay is measured with respect to BR(B+ -> J/Psi K*) and the invariant mass distributions of J/Psi Lambda, J/Psi p and Lambda p systems are investigated. The third analysis uses the data collected by CMS in 2016, corresponsing to a luminosity of 33 fb^-1.
