Studies of Higgs boson production using the H->ZZ->4l decay channel are performed using a data sample corresponding to an integrated luminosity of 2.8 fb-1 of pp collisions at a center-of-mass energy of 13 TeV collected by the CMS experiment at the LHC during 2015. The observed significance for the standard model Higgs boson with mH = 125.09 GeV is 2.5sigma, where the expected significance is 3.4sigma. The model independent fiducial cross section is measured to be sfid. = 2.48+1.48-1.14(stat. +sys.)+0.01-0.04(model dep.) fb. In addition, a search for an additional Higgs boson is performed for a range of masses up to 1 TeV and with various widths, and no significant excess is observed. The results of this search are interpreted in the context of the two Higgs doublet model.
