Detecting the Higgs boson(s) in LambdaSUSY

TL;DR

This paper evaluates the potential for discovering Higgs bosons within the LambdaSUSY model, emphasizing the detection prospects of the lightest and next-to-lightest scalars at the LHC.

Contribution

It provides a detailed analysis of Higgs boson detection prospects in LambdaSUSY, highlighting the enhanced decay modes of the next-to-lightest scalar.

Findings

Next-to-lightest scalar decay modes are more detectable at the LHC.

Scalar masses are increased at tree level due to a large supersymmetric coupling.

The interplay between different scalar states affects discovery strategies.

Abstract

We reconsider the Higgs bosons discovery potential in the LambdaSUSY framework, in which the masses of the scalar particles are increased already at tree level via a largish supersymmetric coupling between the usual Higgs doublets and a Singlet. We analyze in particular the interplay between the discovery potential of the lightest and of the next-to-lightest scalar, finding that the decay modes of the latter should be more easily detected at the LHC.
