Full one-loop electroweak corrections to $h^0(H^0,A^0)H^{\pm }{W}^{\mp }$ associated productions at $e^{+}{e}^{-}$ linear colliders

Abstract

We study the complete one-loop electroweak(EW) corrections to the processes of single charged Higgs boson production associated with a neutral Higgs boson$(h^0,H^0,A^0)$ and a gauge boson $W^{\pm }$ in the framework of the minimal supersymmetric standard model(MSSM). Numerical results at the $SPS1{\mathrm{a}}^{\prime }$ benchmark point as proposed in the SPA project, are presented for demonstration. We find that for the process $e^{+}{e}^{-}\to h^0{H}^{\pm }{W}^{\mp }$ the EW relative correction can be either positive or negative and in the range of $-15$ in our chosen parameter space. While for the processes $e^{+}{e}^{-}\to H^0(A^0)H^{\pm }{W}^{\mp }$ the corrections generally reduce the Born cross sections and the EW relative corrections are typically of order $-10$.
