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

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{sup 0},H{sup 0},A{sup 0}) and a gauge boson W{sup {+-}} in the framework of the minimal supersymmetric standard model (MSSM). Numerical results at the SPS1a{sup u0027} benchmark point as proposed in the SPA project, are presented for demonstration. We find that for the process e{sup +}e{sup -}{yields}h{sup 0}H{sup {+-}}W{sup {+-}} the EW relative correction can be either positive or negative and in the range of -15%{approx}20% in our chosen parameter space. While for the processes e{sup +}e{sup -}{yields}H{sup 0}(A{sup 0})H{sup {+-}}W{sup {+-}} the corrections generally reduce the Born cross sections and the EW relative corrections are typically of order -10%{approx}-20%.
