Tevatron Higgs mass bounds: Projecting U(1)' models to LHC domain

Abstract

We study Higgs boson masses in supersymmetric models with an extra U(1) symmetry to be called U(1)'. Such extra gauge symmetries are urged by the mu problem of the MSSM, and they also arise frequently in low-energy supersymmetric models stemming from GUTs and strings.
