AbstractThe O(alpha (ew)m(t(b))(2)/m(W)(2)) and O(alpha (ew)m(t(b))(4)/m(W)(4)) supersymmetric electroweak corrections to the cross section for W+/-H-/+ associated production at the CERN LHC are calculated in the minimal supersymmetric standard model. Those corrections arise from the quantum effects which are induced by the Yukawa couplings from the Higgs sector and the genuine supersymmetric electroweak couplings involving supersymmetric particles, i.e., chargino-top(bottom)-bottom-squark-(top-squark) couplings, neutralino-top(bottom)-top-squark (bottom-squark) couplings and charged Higgs-boson-top-squark-bottom-squark couplings. The Yukawa corrections can decrease the total cross sections significantly for low tan beta>(*) over bar *(<4) when m(H+)(<300) GeV, which exceed -12%. For high tan beta the Yukawa corrections become negligibly small. The genuine supersymmetric electroweak corrections can increase or decrease the total cross sections depending on the supersymmetric parameters, which are at most a few percent, except the region near the threshold. We also show that the genuine supersymmetric electroweak corrections depend strongly on the choice of tan beta, A(t), M-(Q) over tilde, and mu. For large values of A(t), or large values of mu and tan beta, one can get larger corrections. The corrections can become very small, in contrast, for larger values of M (Q) over tilde.
