Abstract The Large Hadron Collider (LHC) has been extremely successful in its initial few years of its operation. The two general purpose experiments, the CMS and the ATLAS, announced the observation of a Higgs-like boson with mass of approximately 125 GeV using 5.1fb−1 and 5.3fb−1 of the integrated luminosity collected in proton–proton collisions at the s=7TeV and 8 TeV respectively. Since then additional data has been collected by the LHC. This work presents an update on the results of Higgs-like boson using additional ∼7fb−1 of integrated luminosity collected by the CMS experiment at s=8TeV In particular, results from the two most sensitive final states, i.e. H→ZZ→4l and H→γγ are described in detail.
