One of the most promising models beyond the Standard Model is the Minimal Supersymmetric extension to the Standard Model (MSSM). Setting limits on the parameter space of the MSSM is mandatory in order to provide constraints for further experimental and theoretical studies. As with any 2HDM, five different Higgs bosons are predicted. In various scenarios of the MSSM the decay of the heavy scalar Higgs boson H into two W bosons provides sensitivity on two important parameters in the Higgs sector, tanβ and m_A, in a region where analyses of other final states are less sensitive.
In this talk the results of this BSM H→ WW analysis are presented, which show limits in the parameter space of a general 2HDM, as well as model dependent limits of MSSM scenarios. The data used was recorded in 2016 by CMS at a center-of-mass energy of 13 TeV, which corresponds to an intergrated luminosity of 35.9 fb⁻¹.
