Production of Charginos, Neutralinos, and Sleptons at Hadron Colliders

We analyze the production of charginos, neutralinos, and sleptons at the hadron colliders Tevatron and LHC in the direct channels $p\overline{p}/pp\ensuremath{\rightarrow}{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\chi}}}_{i}{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\chi}}}_{j}+X$ and $\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\ell}}{\stackrel{\stackrel{\ifmmode \tilde{}\else \~{}\fi{}}{\ensuremath{\ell}}}{\ifmmode\bar\else\textasciimacron\fi{}}}^{\ensuremath{'}}+X$. The cross sections for these reactions are given in next-to-leading order supersymmetric QCD. By including the higher-order corrections, the predictions become theoretically stable, being nearly independent of the factorization and renormalization scales. Since the corrections increase the cross sections, the discovery range for these particles is extended in the refined analysis.
