Comprehensive Analysis on the Light Higgs Boson Scenario

TL;DR

This paper thoroughly investigates the light Higgs scenario within the non-universal Higgs mass model, considering experimental and cosmological constraints, and finds current LHC data exclude the viable parameter space, suggesting future tests via B_s to mu^+ mu^- measurements.

Contribution

It provides a comprehensive analysis of the light Higgs scenario in NUHM, incorporating multiple constraints and highlighting the current experimental exclusions.

Findings

Current LHC results exclude the allowed parameter space.

Extensions to the model could potentially save the light Higgs scenario.

Future B_s to mu^+ mu^- measurements can test the scenario.

Abstract

Comprehensive analysis on the light Higgs scenario of the minimal supersymmetric standard model is performed in the framework of the non-universal Higgs mass model (NUHM). The NUHM is known to be the simplest framework realizing the light Higgs scenario with the unifications of gaugino and sfermion masses at the scale of grand unified theory being consistent. All important constraints from collider experiments, flavor-changing processes, and cosmological observations are considered in order to clarify the allowed region of the model parameter space, where the Markov Chain Monte Carlo method is used to obtain the region. We show that the region is excluded by current LHC results for the SUSY particle searches. We discuss possible extensions to save the LHS. Even with such extensions, the measurement of B_s to mu^+ mu^- would enable us to test the LHS in the near future.
