Renormalisation group running effects in pp→ tt̅h in the Standard Model Effective Field Theory
arxiv(2023)
摘要
We study the effects of renormalisation group running of the Wilson
coefficients in Standard Model Effective Field Theory, using the process pp
→ t t̅h 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.
