  If light--flavor squarks and gluinos are indeed heavy and chargino pair
production is plagued with overwhelming backgrounds, pair production and
associated production of stops and charginos will become the key signatures in
the upcoming LHC runs. We present fully automated next-to-leading order
predictions for heavy flavor squark production at the LHC, including
stop-chargino associated production, based on MadGolem. We compute the total
and differential NLO rates for a variety of MSSM scenarios with a light third
generation. We focus on theoretical uncertainties on differential rates,
including a comparison to multi-jet merging and the impact of bottom parton
densities for stop-chargino associated production. We find that for the
associated production channel the rates can reach tens of femtobarns, but the
scale dependence does not provide a conservative estimate of the theoretical
uncertainties.
