Abstract:

This Letter presents a search for a heavy neutral particle decaying into an opposite-sign different-flavor dilepton pair, e±μ±, e±τ±, or μ±τ± using 20.3 fb-1 of pp collision data at s=8 TeV collected by the ATLAS detector at the LHC. The numbers of observed candidate events are compatible with the standard model expectations. Limits are set on the cross section of new phenomena in two scenarios: the production of ντ in R-parity-violating supersymmetric models and the production of a lepton-flavor-violating Z′ vector boson. © 2015 CERN, for the ATLAS Collaboration.

  • ATLAS uses a right-handed coordinate system with its origin at the nominal interaction point in the center of the detector and the (Equation presented) axis along the beam direction. The (Equation presented) axis points toward the center of the LHC ring, and the (Equation presented) axis points upward. Cylindrical coordinates (Equation presented) are used in the transverse plane, (Equation presented) being the azimuthal angle around the beam direction. Pseudorapidity is defined in terms of the polar angle (Equation presented) as (Equation presented). Transverse projections are defined relative to the beam axis; (2014) Eur. Phys. J.
