Phenomenological study of weakino pair production processes in the MSSM at next-to-leading order — Julien Baglio, Barbara Jäger, and •Matthias Kesenheimer — Eberhard Karls Universität Tübingen

The Minimal Supersymmetric Standard Model (MSSM) predicts the existence of eight weakly interacting particles which are linear combinations of a higgsino and one wino or one bino. These states are called charginos for the electrically charged particles or neutralinos for the neutral particles. Additionally, if R-parity is conserved every weakino production process with following decay results in at least one stable neutralino, which is a good candidate for a dark matter particle. By studying weakino production processes we can gain information about dark matter and SUSY in general. Furthermore, for the analysis of experimental data precise theoretical calculations of production cross sections are essential. With new constrains on SUSY models, we perform a phenomenological study including higher order QCD corrections of chargino and neutralino production processes. Preliminary results of the production cross-section at √s=14 TeV of p p collisions are presented.
