Two loops, four tops and two schemes: a renormalization story
Stefano Di Noi, Ramona Gröber
We calculate the four-top quark operator contributions to the two-loop renormalization constants of the fermion and gluon fields, necessary to obtain the renormalization group equa…

Renormalization group running effects in in the SMEFT
Stefano Di Noi
We analyze the effects of renormalization group running of the Wilson coefficients in the SMEFT in the context of single Higgs production in association with a top-antitop pair. In…

Subleading operators and gamma5-scheme dependence in SMEFT for Higgs boson pair production
Stefano Di Noi, Ramona Gröber, Gudrun Heinrich +3
The calculation of contributions from the chromomagnetic and four-top-quark-operators within Standard Model Effective Field Theory (SMEFT) to Higgs boson pair production in gluon f…
