Searches for New Physics in Rare Decays of Heavy Flavors at CMS

As direct searches for beyond the Standard model physics at the LHC have not been successful, more and more attention is drawn to the indirect searches. In particular, rare decays of beauty and charm hadrons present a sensitive laboratory for BSM physics and new particles, since they can contribute to loop diagrams, even if their mass is much heavier than that of the final-state particles. In this report, several recent results of the CMS collaboration on rare processes with heavy flavor mesons are discussed. The results are based on pp collision data collected at centre-of-mass energies of 13 and 13.6 TeV.
