Description
The production of coloured supersymmetric particles is an important
SUSY discovery channel at the LHC. Therefore it is essential that
the theoretical predictions for squark and gluino production cross
sections are known with high accuracy.
In this talk I will focus on the effects of soft gluon emission on
the total cross sections for squark-antisquark and gluino-pair
production. After a short review of the QCD resummation method,
used to systematically treat soft parts of higher order corrections,
I will report its application to the hadronic sparticle production
processes. Concluding, I will discuss the size of the soft gluon
corrections and the reduction of the theoretical error related to
the scale dependence.
