Off-shell Higgs boson couplings measurement using $H$ → $ZZ$ → 4$l$ events at High Luminosity LHC

Several studies have shown that the high-mass off-peak regions in the $H$ → $ZZ$ and $H$ → $WW$ channels above the 2$m$$_{V}$ threshold ($V$ = $W$,$Z$) have sensitivity to off-shell Higgs production and interference effects. This feature can be exploited to characterize the Higgs boson off-shell sig...

description Several studies have shown that the high-mass off-peak regions in the $H$ → $ZZ$ and $H$ → $WW$ channels above the 2$m$$_{V}$ threshold ($V$ = $W$,$Z$) have sensitivity to off-shell Higgs production and interference effects. This feature can be exploited to characterize the Higgs boson off-shell signal strength and its associated couplings. This note reports on prospects on the Higgs boson off-shell couplings in the High-Luminosity LHC (HL-LHC) scenario, assuming 300 fb$^{−1}$ and 3000 fb$^{−1}$ of collision data collected at √s=14 TeV, using a simplified version of the published $H$ → $ZZ$ → 4$l$ off-shell couplings analysis.
