Status of G2HDM with right handed neutrino coupling in the light of b → cτν anomalies

Recent experimental measurements of several observables in semileptonic B meson decays have pointed towards the possibility of new physics. The LHCb collaboration has reported a significant deviation, exceeding [Formula: see text], in the combined measurement of the ratio of branching ratios [Formula: see text] from the predictions of the standard model. Furthermore, other observables, such as [Formula: see text], [Formula: see text], [Formula: see text], and [Formula: see text] in the [Formula: see text] transition, have also exhibited noticeable deviations from the standard model predictions. Motivated by these anomalies in the [Formula: see text] transitions, we perform a log-likelihood fit incorporating new physics coming from right-handed neutrino couplings and explored the implications of a charged Higgs boson within a generic two Higgs doublet model (G2HDM). Our comprehensive analysis, focused on the [Formula: see text] and [Formula: see text] final states, was performed using the High Luminosity run of the Large Hadron Collider (HL-LHC). We demonstrate that HL-LHC has the sensitivity to exclude the remaining allowed region in G2HDM model in explaining these anomalies with charged Higgs boson coupled to right-handed neutrino.
