| الوصف: | We explore the production and the possible detection of a charged scalar Higgs pair $H^-H^+$ decaying into a final state $\mu\nu_{\mu}cb$ in proton-proton collisions, i.e, $pp\to H^- H^+\to \mu\nu_{\mu} cb$. These charged scalars are predicted in the Two-Higgs Doublet Model of type III (2HDM-III), particularly we analyze masses of such a particle of the order of the top quark mass. The analysis is applied to the Large Hadron Collider (LHC) and its next step, the High Luminosity LHC (HL-LHC). As a test and validation of the model, we identify regions of the 2HDM-III parameter space that accommodate the current excess of events at $3\sigma$ in the process $\mathcal{BR}(t\to H^{\pm}b)\times \mathcal{BR}(H^{\pm}\to cb)$ for $M_{H^{\pm}}=130$ GeV reported by ATLAS collaboration. Additional experimental constraints are also included. Based on it, we propose realistic scenarios that could be brought to experimental scrutiny at the LHC and HL-LHC. Assuming the best scenario, we predict a signal significance of $5\sigma$ for the charged scalar boson mass $M_{H^{\pm}}$ in the $120-240$ GeV interval. Comment: 31 pages, 22 figures, 9 tables |
