QCD corrections to top quark spin correlations at hadron colliders

Abstract

Future hadron collider experiments will allow for a detailed investigation of $t\bar{t}$ spin correlation effects. In this talk, recent progress in the theoretical description of these effects is reported. In particular, next-to-leading order results for the $t\bar{t}$ spin correlations in $q\bar{q}\to t\bar{t}X$ are presented, using various spin quantization axes.
