20893por Calandri, Alessandro“…ZZ$\rightarrow$4l, ZZ$\rightarrow$2l2$\nu$ and WW$\rightarrow$l$\nu$l$\nu$, the results lead to an observed (expected) 95% C.L. upper limit on the Higgs boson total width of 22.7 (33.0) MeV (4.2 MeV is the Standard Model predicted Higgs width at $m_{H}$=125 GeV). The last section of the thesis is devoted to the evaluation of the Higgs width at $\sqrt{s}$=14 TeV in the high luminosity scenario (High Luminosity LHC), 300 fb$^{−1}$ and 3000 fb$^{−1}$, by employing the same techniques exploited in the previous Run 1 analysis at $\sqrt{s}$=8 TeV.…”
