Triplet with a doubly-charged lepton at the LHC

Understand

We studied the signatures of an electroweak SU(2) lepton triplet which contains a doubly charged heavy lepton.

• The most interesting and easily detected final states are originating from the doubly charged lepton pair and single production, that we analyzed at a center of mass energy of 14 TeV.
• We propose useful kinematic cuts to reduce the backgrounds and computed the integrated luminosity needed to discover or exclude the doubly charged leptons for various masses.
