Phenomenology of light remnant doubly charged Higgs fields in the supersymmetric left-right model

Abstract

It has recently shown that in supersymmetric left-right models with automatic R-parity conservation, the theory below the $W_R$ scale is given by MSSM with massive neutrinos and a pair of doubly charged superfields with masses in the 100 GeV range (with or without an extra pair of heavy Higgs doublets (M \geq 10 TeV) depending on the model). In this paper we study the unification prospects for such theories and their phenomenological implications for collider experiments. We study two versions of the theory, one with supersymmetry breaking transmitted via the gauge and another where the same occurs via gravitational forces. We point out that looking at multi $τ$ final states can considerably constrain the parameter space of the model.
