Studies of Higgs boson production in the four-lepton final state at sqrt(s) = 13 TeV

Studies of Higgs boson production are presented using the $\mathrm{H}\rightarrow\mathrm{Z}\mathrm{Z}\rightarrow4\ell$ ($\ell=\mathrm{e},\mu$) 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 cente...

description Studies of Higgs boson production are presented using the $\mathrm{H}\rightarrow\mathrm{Z}\mathrm{Z}\rightarrow4\ell$ ($\ell=\mathrm{e},\mu$) 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 $2.5\sigma$, where the expected significance is $3.4\sigma$. The model independent fiducial cross section is measured to be $\sigma_{\mathrm{fid.}}=2.48^{+1.48}_{-1.14}(\mathrm{stat. \oplus sys.})^{+0.01}_{-0.04}(\mathrm{model~dep.})~\mathrm{fb}$. 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.
