Top-squark pair production at the LHC: a complete analysis at next-to-leading order

Understand

We present a complete next-to-leading order study of top-squark pair production at the LHC, including QCD and EW corrections.

• The calculation is performed within the Minimal Supersymmetric Standard Model and numerical results are presented for parameter regions compatible with the observed Higgs boson.
• We employ the most recent parton distribution functions including QED corrections and we find NLO EW corrections to the inclusive stop-pair production cross section up to $25 - 30\%$ compared to the leading-order prediction.
• Besides corrections to inclusive cross sections also important kinematic distributions are investigated.
