Description
Charged Higgs-pair production at hadron colliders provides an option to obtain information about the trilinear couplings involving charged Higgs states of BSM Higgs potentials. We analyze the corresponding production modes, Drell–Yan-like production, gluon fusion and vector-boson fusion at next-to-leading order with respect to the corresponding uncertainties originating from the scale dependence, the parton-density functions and strong coupling $\alpha_s$ at the LHC. We observe a significant reduction of the scale dependences after including the related radiative corrections. This analysis allows for a sophisticated interpretation of experimental measurements, once charged Higgs states will be observed.
