Description
The pair production of squarks is one of the main search channels for
supersymmetry at the LHC. For the interpretation of experimental data
precise theoretical predictions are crucial. The work presented in the
talk contributes to this effort by providing a fully differential
calculation of the NLO SUSY-QCD corrections to the on-shell production
of squark pairs supplemented by the decay of the squarks to the lightest
neutralino and a quark in the MSSM.
However, for precise simulations at the level of the actually measured
experimental observables a combination of these fixed-order NLO calculations
and parton showers is mandatory. To this end, the process was implemented in
the Powheg-Box framework and interfaced with different parton shower programs.
We study the impact of the NLO corrections on the differential scale dependence
and K-factors and investigate the parton shower effects.
