Abstract

We study the effects of renormalisation group running of the Wilson coefficients in Standard Model Effective Field Theory, using the process pp → t th as a showcase. We consider both strong and top Yukawa running effects, since the latter can be relevant in presence of large Wilson coefficients. We study the difference between the use of a dynamical and fixed renormalisation scale by exploring different scenarios for the higher-dimensional operators at the high energy scale of new physics, assumed to be at the TeV scale.
