Higgs, chargino and neutralino mass spectra in RPV U(1)′ model

Abstract

— We examine the sensitivity of the particle spectrum to the parameters of the U(1)′-extended MSSM with R-parity violation. This model provides a simultaneous solution to both the μ-problem and the proton decay problem which plague the MSSM. We focus on variations of neutralino, chargino and Higgs boson masses in various lepton number violations couplings, scanning over all the space to find allowed regions of the parameter space consistent with the experimental constraints for these masses.
