Charged heavy lepton pair production in ATLAS: 2(2,\mu)+4 jets channel

The ATLAS sensitivity to sequential charged heavy lepton pair production, as predicted, in particular, by various models with an extended gauge sector has been studied. Both the Drell-Yan and the gluon - gluon production processes are considered. Assuming Standard Model couplings, the discovery potential for the $L^{\pm}\to (e,\mu )^{\pm}Z^0\to ~(e,\mu )^{\pm}-dijet$ decay channel as a function of heavy lepton mass $M_{L}$ and $Z'$ boson mass $M_{Z'}$ is presented. For an integrated luminosity of 30~fb$^{-1}$, it was found that ATLAS could discover this charged heavy lepton up to 0.9~TeV/c$^2$ and the discovery limit is pushed up to 1.0~TeV/c$^2$ for an integrated luminosity of 300~fb$^{-1}$.
