New results for the 4-loop massive cusp anomalous dimension
Nikolaos Kidonakis
I present new results for the massive cusp anomalous dimension at four loops in QCD. I combine partial exact and conjectured analytical expressions with an approximation that is ba…
NLO soft-gluon corrections for production
Nikolaos Kidonakis, Kaan Şimşek
We calculate soft-gluon corrections for production through next-to-next-to-next-to-leading-order (NLO) in one-particle-inclusive (1PI) kinematics. We use these results to…
production as a probe of dimension-6 SMEFT at higher orders
Nikolaos Kidonakis, Kaan Şimşek
We study top-antitop pair production in proton-proton collisions within the Standard Model Effective Field Theory (SMEFT) at dimension 6. We focus on the top chromomagnetic operato…
Constraining dimension-6 SMEFT with higher-order predictions for
Nikolaos Kidonakis, Kaan Şimşek
We study single-top production in association with a boson at the Large Hadron Collider (LHC) as a probe of dimension-6 Standard Model effective field theory (SMEFT) at leading…
