Search for additional Higgs bosons decaying into W⁺ W⁻ in the di-leptonic final state with CMS using full Run 2 data — Olena Hlushchenko, Sven Krausse, Wolfgang Lohmann, •Dennis Roy, Hale Sert, Sebastian Siebert, Achim Stahl, and Alexander Zotz — RWTH Aachen University - Physics Institute III B, Aachen, Germany

Using proton-proton collision data, corresponding to an integrated luminosity of 137.1 fb⁻¹ recorded by CMS during Run 2, searches for new particles are performed with unprecedented sensitivity. The high mass H→ WW analysis aims to search for resonances at masses up to 5 TeV. Their origin might be an additional Higgs boson, such as one expected in extended Higgs sectors, e.g. the Two Higgs Doublet Model (THDM) and a more specific case, the Minimal Supersymmetric Standard Model (MSSM). In case no signal is found, new limits on THDM and MSSM scenarios are set. This analysis is performed in the semi-leptonic and the di-leptonic final state. The status of the full Run 2 analysis in the di-leptonic final state is presented in this talk.
