Constraints on U ( 1 ) L μ ? L τ from LHC data

摘要

In this study, we apply LHC data to constrain the extension of the Standard Model by an anomaly–freeU(1)Lμ?Lτgauge group; this model contains a new gauge boson (Z′) and a scalar dark matter particle (?DM). We recast a large number of LHC analyses of multi–lepton final states by the ATLAS and CMS collaborations. We find that for10GeV
