Measurement of the ratio of the B c + → J / ψ τ + ν τ and B c + → J / ψ μ + ν μ branching fractions using three-prong τ lepton decays

V. Chekhovsky · A. Hayrapetyan · V. Makarenko · A. Tumasyan · y 196 más

The ratio between the B c + → J / ψ τ + ν τ and B c + → J / ψ μ + ν μ branching fractions is measured using a data sample of proton-proton collisions collected by CMS at a center-of-mass energy of 13 TeV in the years 2016–2018 and corresponding to an integrated luminosity of 138 fb − 1 . The J / ψ meson is identified t...
