  We present a calculation of the next-to-leading order QCD corrections to
weakino+squark production processes at hadron colliders and their
implementation in the framework of the POWHEG-BOX, a tool for the matching of
fixed-order perturbative calculations with parton-shower programs. Particular
care is taken in the subtraction of on-shell resonances in the real-emission
corrections that have to be assigned to production processes of a different
type. In order to illustrate the capabilities of our code, representative
results are shown for selected SUSY parameter points in the pMSSM11. The
perturbative stability of the calculation is assessed for the $ pp \rightarrow
\tilde{\chi}^0_1 \tilde{d}_L $ process. For the squark+chargino production
process $ pp \rightarrow \tilde{\chi}_1^- \tilde{u}_L $ distributions of the
chargino's decay products are provided with the help of the decay feature of
PYTHIA 8.
