Associated tW production at lhc: A Complete calculation of electroweak supersymmetric effects at one loop

We compute, in the MSSM framework, the total electroweak contributions at one loop for the process $pp\ensuremath{\rightarrow}tW+X$, initiated by the parton process $bg\ensuremath{\rightarrow}tW$. The supersymmetric effect is analyzed for various choices of the SUSY benchmark points. Choosing realistic unpolarized and polarized experimental quantities, we show the size of the various effects and discuss their dependence on the MSSM parameters.
