description | Abstract
Results are reported from a search for the lepton flavor violating decay τ → 3μ in proton-proton collisions at
s
$$ \sqrt{\mathrm{s}} $$
= 13 TeV. The data sample corresponds to an integrated luminosity of 33.2 fb−1 recorded by the CMS experiment at the LHC in 2016. The search exploits τ leptons produced in both W boson and heavy-flavor hadron decays. No significant excess above the expected background is observed. An upper limit on the branching fraction ℬ(τ → 3μ) of 8.0 × 10−8 at 90% confidence level is obtained, with an expected upper limit of 6.9 × 10−8. |
