Description

Tests of lepton flavor conservation and universality offer a sensitive probe for physics beyond the Standard Model (SM), with several BSM scenarios predicting deviations accessible at the CMS experiment. This contribution presents an overview of CMS results from searches for Lepton Flavor Violation (LFV) and Lepton Flavor Universality (LFU) violation in proton-proton collisions at a center-of-mass energy of 13 TeV, with a focus on heavy flavor decays. The results include a search for LFV in the charged sector via the $\tau \to 3\mu$ decay, as well as tests of LFU in the $B \to K\ell\ell$ and $B_c \to J/\psi,\ell\nu$ channels.
