Description

Motivated by the recent search for bbτ τ final state conducted by the CMS experiment, we would like to address the study of signal and background for such a final state within the so-called 2HDM Type-I. We investigate the scope of the LHC in accessing the process gg → H → hh → b b τ τ by performing a Monte Carlo (MC) analysis aimed at extracting this signal from the SM backgrounds, in the presence of a dedicated trigger choice and kinematical selection. We prove that some sensitivity to such a channel exists already at Run 3 of the LHC while the High-Luminosity LHC (HL-LHC) will be able to either confirm or disprove this theoretical scenario over sizable regions of its parameter space.
