Higgs, di-Higgs and tri-Higgs production via SUSY processes at the LHC with 14 TeV

TL;DR

This paper explores how supersymmetric particle decays at the 14 TeV LHC can produce multiple Higgs bosons, offering distinctive signatures for new physics and aiding the interpretation of Higgs measurement deviations.

Contribution

It systematically analyzes SUSY processes that produce Higgs, di-Higgs, and tri-Higgs events, identifying parameter regions consistent with data and predicting observable signatures.

Findings

Large regions of parameter space predict significant Higgs production rates.

Higgs events from SUSY processes can produce diverse detector signatures with missing transverse momentum.

Such signatures are promising for early detection of new physics at the LHC.

Abstract

We have systematically investigated the production of a Higgs boson with a mass of about $125$ GeV in the decays of supersymmetric particles within the phenomenological MSSM (pMSSM). We find regions of parameter space that are consistent with all world data and that predict a sizeable rate of anomalous Higgs, di-Higgs and even tri-Higgs events at the 14 TeV LHC. All relevant SUSY production processes are investigated. We find that Higgs bosons can be produced in a large variety of SUSY processes, resulting in a large range of different detector signatures containing missing transverse momentum. Such Higgs events are outstanding signatures for new physics already for the early 14 TeV LHC data. SUSY processes are also important to interprete deviations found in upcoming Standard Model Higgs and di-Higgs production measurements.
