| Abstract: | Inspired by the recent single $e\mu$ event at 2.1 TeV invariant mass from the ATLAS at $\sqrt{s}$ TeV with 3.2 fb$^{-1}$ luminosity, we propose an explanation using a $Z'$ gauge boson, which possesses lepton-flavor-changing neutral currents to charged leptons. We assume that the left-handed charged-lepton mixing matrix equals to the PMNS matrix. There are indeed some parameter regions, where the $Z'$ can generate a large enough $e\mu$ production cross section, while at the same time satisfies various observables from lepton-flavor violation and other constraints from the LHC. |
