Abstract

In the context of Left-Right symmetry, we revisit the Keung-Senjanović production of right-handed W_R bosons and heavy neutrinos N at high energy colliders. We develop a multi-binned sensitivity measure and use it to estimate the sensitivity for the entire range of N masses, spanning the standard and merged prompt signals, displaced vertices and the invisible N region. The estimated sensitivity of the LHC with 300/fb integrated luminosity ranges from 5 to beyond 7 TeV, while the future 33(100) TeV collider's reach with 3/ab extends to 12(26) TeV.
