Abstract

Integrated fiducial cross sections for the production of four leptons via the H $\rightarrow$ 4$\ell$ decays $(\ell = e,\mu)$ are measured in pp collisions at $\sqrt{s}$ = 7,8 and 13 TeV. Measurements are performed with data corresponding to integrated luminosities of 5.1 fb$^{-1}$1 at $\sqrt{s}$ = 7 TeV, 19.7 fb$^{-1}$ at $\sqrt{s}$ = 8 TeV and 12.9 fb$^{-1}$ at $\sqrt{s}$ = 13 TeV, collected with the CMS experiment at the LHC. Differential cross sections are measured as a function of transverse momentum of four-lepton system and accompanying jet multiplicity using 8 and 13 TeV data set. All cross sections are measured within a fiducial phase space defined by the requirements on lepton kinematics and event topology. The integrated H $\rightarrow$ 4$\ell$ fiducial cross section is measured to be 0:56$^{+0:67}_{-0:44}$ (stat:)$^{+0:21}_{-0:06}$ (sys:) $\pm$ 0:02(model) fb at 7 TeV, 1:11$^{+0:41}_{-0:35}$ (stat:)$^{+0:14}_{-0:10}$ (sys:)$^{+0:08}_{-0:02}$ (model) fb at 8 TeV and 2:29$^{+0:74}_{-0:64}$(stat:)$^{+0:30}_{-0:23}$(sys:)$^{+0:01}_{-0:05}$(model)fb at 13 TeV. The measurements are found to be compatible with the theoretical calculations based on the standard model.
