Description
This contribution presents recent results from the CMS experiment at the LHC on searches for Lepton Flavor Violation (LFV) and Lepton Flavor Universality (LFU) violation in heavy flavour decays involving tau leptons. The tau acts as a powerful probe for physics beyond the Standard Model (BSM), particularly in the low transverse momentum (p_T) regime typical of B hadron decays. We report on a search for charged LFV via the decay \tau \to 3\mu, as well as on tests of LFU in the rare decay B_c \to J/\psi \tau \nu.
