Higher-order soft corrections to squark hadro-production

Understand

We present new predictions for the total cross section of squark pair-production at Tevatron and LHC through next-to-next-to-leading order within the Minimal Supersymmetric Standard Model.

• The results are based on the numerically dominant soft corrections.
• They are exact in all logarithmically enhanced terms near threshold, include the Coulomb corrections at two loops and exact scale dependence.
• We translate the increased total cross section at next-to-next-to-leading order into improved exclusion limits for squark masses and we investigate the scale dependence as well as the sensitivity on the parton luminosity.
