Next-to-leading order accuracy and spin effects for squark-gluino production and decay

The search for supersymmetry is a central task of the Large Hadron Collider. The interpretation of the experimental data requires accurate and flexible theoretical predictions. We present a new calculation of the next-to-leading order supersymmetric-QCD corrections to the decay of squarks and gluinos. In particular, we provide fully differential cross sections. We will focus our discussion on the production and decay of squarks and gluinos. Gluinos decay into squarks and jets while squarks directly decay into the lightest supersymmetric particle and jets. In this process, the spin of the gluino can have a substantial effect. The methods used and some exemplary results are presented.
