Studies of Higgs boson production are presented using the () decay channel. These studies are performed using a data sample corresponding to an integrated luminosity of 2.8~\mathrm{fb}^{-1} of pp collisions at a center-of-mass energy of 13~\mathrm{TeV} collected by the CMS experiment at the LHC during 2015. The observed significance for the standard model Higgs boson with m_{\mathrm{H}}=125.09~\mathrm{GeV} is , where the expected significance is . The model independent fiducial cross section is measured to be \sigma_{\mathrm{fid.}}=2.48^{+1.48}_{-1.14}(\mathrm{stat. \oplus sys.})^{+0.01}_{-0.04}(\mathrm{model~dep.})~\mathrm{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.
