Search for DiHiggs production H → hhS in an extended NMSSM Higgs sector with CMS — •Martin Marz, Felix Heyen, Ulrich Husemann, Nikita Shadskiy, Michael Waßmer, and Roger Wolf — Institute of Experimental Particle Physics (ETP), Karlsruhe Institute of Technology (KIT)
The search for new physics is essential to validate or exclude theoretical models. For this purpose, models including additional non-standard-model-like Higgs bosons are of great interest. The Next-to-Minimal Supersymmetric Standard Model (NMSSM) for example predicts such additional Higgs bosons. Especially the decay of a heavy Higgs boson H into two lighter Higgs bosons ( hS, h ), allows for a rich experimental program. Here h is the observed Higgs boson with properties as expected by the SM.
The analysis presented in this talk is intended to use a general re-reconstruction of the LHC run 2 dataset from 2018 to profit from the best understanding of physics objects measured and reconstructed with the CMS detector in the search of new physics. The decay channel h → bb, hS → τ τ and the subsequent decay of the tau pair into a muon and hadrons is studied to add to a recently published analysis (JHEP 11 (2021) 057) by the CMS collaboration.
