Discovering Chiral Higgsinos at the LHC

Abstract

The concept of chirality is extended to the Minimal Supersymmetric Standard Model (MSSM) and the mu term is forbidden by a gauged U(1)' symmetry. R-parity automatically emerges after symmetry breaking, suppressing proton decay and protecting the LSP. Exotics charged under the SM pose a challenge to traditional SU(5) unification, but unification is still implemented in deconstructed GUTs. Because of the multitude of additional states to the MSSM, the Z' has a large width, and the SM background, neglected in previous theoretical studies, becomes important for Z' discovery. As a result, the LHC reach is reduced from 3.2 TeV, for a Z' with SM decays, to 1.5 TeV, when additional decay channels are included. This model also predicts possibly long-lived colored and electroweak exotics.
