Search for additional Higgs bosons produced in association with b quarks and decaying into two b quarks — •Paul Asmuss — DESY Hamburg

A huge breakthrough in particle physics was achieved with the discovery of the Higgs boson in 2012, which was followed by precision measurements of its properties. So far, the discovered particle is found to be in good agreement with the predictions of the Standard Model, but there is still sizable room for theories with extended Higgs sectors, like Supersymmetry or general Two Higgs Doublet Models. Besides additional Higgs bosons, these models may also feature a significant enhancement of the Higgs boson coupling to b quarks. In this analysis, heavy neutral Higgs bosons are targeted which decay into two b quarks and are produced in association with one or two further b quarks, resulting in a fully hadronic final state and focused on masses between 250 GeV and 1.6 TeV. The search is performed with data collected in 2017 and 2018 with the CMS detector at the LHC at a center-of-mass energy of 13 TeV.
