Search for additional Higgs bosons decaying to a pair of W bosons in the semi-leptonic final state with the CMS detector using full Run 2 dataMate Farkas, Olena Hlushchenko, Wolfgang Lohmann, Dennis Roy, Hale Sert, •Sebastian Siebert, Achim Stahl, Lucas Wiens, and Alexander Zotz — III.

During Run 2 of the LHC an integrated luminosity of 137 fb−1 at √s = 13 TeV was recorded by the CMS detector. Apart from measuring properties of known particles more precisely, it is also expected that new particles might be discovered with such a large dataset. Additional heavy Higgs bosons are suggested by many theories beyond the standard model. The high mass HWW analysis studies gluon-gluon fusion and vector-boson fusion as Higgs production mechanisms. The analysis aims to find Higgs-like resonances in the mass region from 115 GeV/c2 to 5000 GeV/c2 or set exclusion limits in the context of MSSM and also two-Higgs-doublet scenarios. This talk presents the status and future plans in the semi-leptonic channel.
