Signatures of gaugino mass non-universality in cascade Higgs production at the LHC

TL;DR

This paper investigates how non-universal gaugino masses affect Higgs production via supersymmetric cascades at the LHC, revealing potential signatures of gaugino mass non-universality in Higgs production rates.

Contribution

It introduces a comprehensive analysis of supersymmetric cascades with non-universal gaugino masses and identifies observable effects on Higgs production ratios at the LHC.

Findings

Deviations in Higgs production rates indicate gaugino mass non-universality.

Relative production rates of lightest and charged Higgses serve as signatures.

Non-universality impacts cascade decay patterns and Higgs signatures.

Abstract

Supersymmetric cascades, involving charginos and neutralinos at various stages, contribute in a significant way to Higgs production at the LHC. We explore the nature of such cascades, completely relaxing the universality of the gaugino masses. It is found that the deviation from the scenario with universal gaugino masses would be reflected in the relative production rates for the lightest Higgs and the charged Higgses, two characteristic particles of an extended Higgs sector.
