Higgs Mass Prediction with Non-universal Soft Supersymmetry Breaking in MSSM

TL;DR

This paper predicts the Higgs boson mass within the MSSM considering non-universal soft SUSY breaking parameters, using experimental inputs and fixed point analyses, resulting in specific mass estimates for different parameter regimes.

Contribution

It introduces a detailed calculation of the Higgs mass in MSSM with non-universal boundary conditions, incorporating fixed point behavior and experimental inputs, providing refined mass predictions.

Findings

Higgs mass estimated at ~93 GeV for low tanβ

Higgs mass around 125.7 GeV for large tanβ with μ > 0

Predictions depend on soft SUSY breaking parameters and boundary conditions

Abstract

In the framework of the MSSM the non-universal boundary conditions of soft SUSY breaking parameters are considered. Taking as input the top, bottom and Z-boson masses, the values of the gauge couplings at the EW scale and the infrared quasi-fixed points for Yukawa couplings and the soft parameters the mass of the lightest CP-even Higgs boson is found to be m_h=92.7^{+10}_{-4.9} +- 5 +- 0.4 GeV/c^2 for the low \tan\beta case and m_h=125.7^{+6.4}_{-9.0} +- 5 +- 0.4 GeV/c^2 (\mu > 0) or m_h =125.4^{+6.6}_{-9.0} +-5 +- 0.4 GeV/c^2 (\mu < 0) in the case of large $\tan\beta$.
