Improving predictions for coloured SUSY particle production with the help of resummation
Anna Kulesza (RWTH Aachen)


The dominant production processes of supersymmetric particles at the LHC are those involving production of a pair of coloured particles, i.e.
squarks and gluinos. In this talk I will discuss the effects of soft gluon emission on the pair-production of squarks and gluinos in hadronic collisions. The soft gluon effects provide a major contribution to higher order QCD corrections and can be treated systematically to all orders by means of resummation techniques. I will report on the calculation of the threshold-resummed total cross sections for all squark and gluino pair-production processes in hadronic collisions. The predictions for these cross sections at the LHC with 7 TeV collision energy will be presented.
