Searches for an additional heavy scalar resonance have been performed by CMS with data collected during 2015 ($2.3$ fb$^{-1}$) and 2016 ($12.9$ fb$^{-1}$) of the LHC at 13 TeV. This document reports searches in the diboson decay channels WW and ZZ. Exclusion limits have been set for different hypotheses: model in-dependent scalar boson, narrow-resonance, Electroweak Singlet model and 2HDM. No excess of events is found over the Standard Model background-only expectation.
