Studies of Higgs boson production in the four-lepton final state at $\sqrt{s}= $ 13 TeV
Abstract: Studies of Higgs boson production are presented using the $ \mathrm{H} \rightarrow \mathrm{Z} \mathrm{Z} \rightarrow 4\ell $ ($\ell=\mathrm{e},\mu$) decay channel. These studies 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 $ m_{\mathrm{H}}= $ 125.09 GeV is 2.5$\sigma$, where the expected significance is 3.4$\sigma$. The model independent fiducial cross section is measured to be $\sigma_{\mathrm{fid.}}=$ 2.48$^{+1.48}_{-1.14}$ (stat $\oplus$ syst) $^{+0.01}_{-0.04}$ (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.
