Abstract

Latest results of searches for heavy Higgs bosons in fermionic final states are presented using the CMS detector at the LHC. Results are based on pp collision data collected at centre-of-mass energies of 8 and 13 TeV which have been interpreted according to different extensions of the Standard Model such as MSSM, 2HDM, and NMSSM. These searches look for evidence of other scalar or pseudoscalar bosons, in addition to the observed SM-like 125 GeV Higgs boson, and set 95% confidence level upper limits in fermionic final states and benchmark models explored. The talk reviews briefly the major results obtained by the CMS Collaboration during Run I, and presents the most recent searches performed during Run II.

Highlights

Heavy Higgs Boson Searches at CMSThe Minimal Supersymmetric Standard Model (MSSM) was originally proposed around the eighties of the last century[1,2,3]
The charged Higgs boson searches have been performed via final states of τ ν and tb[16], which could be very important for further constraints of the MSSM parameter space
Neutral MSSM Higgs Boson search via μμ The MSSM Higgs boson to μμ decay mode has been presented with relatively low systematic uncertainties[15]

Summary

Introduction

Heavy Higgs Boson Searches at CMSThe Minimal Supersymmetric Standard Model (MSSM) was originally proposed around the eighties of the last century[1,2,3]. After the discovery of the standard model like Higgs boson, the MSSM model has become one of the benchmark scenarios for additional Higgs boson searches at the CMS4 experiment. Neutral Higgs bosons have been searched via three fermionic final states τ τ 8,9,10,11, bb[13,14], and μμ[15].
