Exceeding the MSSM Higgs Mass Bound in a Special Class of U(1) Gauge Models

TL;DR

This paper discusses a specific supersymmetric U(1) gauge extension of the standard model that naturally avoids anomalies and allows the lightest Higgs boson to surpass the MSSM mass limit, aligning with current LHC findings.

Contribution

It analyzes a 2002 anomaly-free U(1) gauge model that permits a Higgs mass above the MSSM bound without requiring a mu term.

Findings

The model is anomaly-free and conserves baryon and lepton numbers.

It allows the Higgs boson to have a mass exceeding 130 GeV.

The model aligns with current LHC Higgs data.

Abstract

A special class of supersymmetric U(1) gauge extensions of the standard model was proposed in 2002. It is anomaly-free, has no mu term, and conserves baryon and lepton numbers automatically. It also allows the lightest Higgs boson to have a mass exceeding the MSSM (Minimal Supersymmetric Standard Model) bound, i.e. about 130 GeV, which is of current topical interest from LHC (Large Hadron Collider) data. This and other new aspects of this 2002 proposal are discussed.
