Search for charged-lepton-flavor violating μτqt interactions in top-quark production and decay in pp collisions at SQUARE ROOTs = 13 TeV with the ATLAS detector at the LHC
Original language description
A search for charged-lepton-flavor violating μτqt (q 1/4 u, c) interactions is presented, considering both top-quark production and decay. The data analyzed correspond to 140 fb-1 of proton-proton collisions at a center-of-mass energy of SQUARE ROOTs = 13 TeV recorded with the ATLAS detector at the Large Hadron Collider. The analysis targets events containing two muons with the same electric charge, a hadronically decaying τ-lepton and at least one jet, with exactly one b-tagged jet, produced by a μτqt interaction.Agreement with the Standard Model expectation within 1.6 standard deviations is observed, and limits are set at the 95% confidence level (CL) on the charged-lepton-flavor violation branching ratio of Bðt RIGHTWARDS ARROW μτqÞ < 8.7 x 10-7. An effective field theory interpretation is performed yielding 95% CL limits on Wilson coefficients, dependent on the flavor of the associated light quark and the Lorentz structure of the coupling.
