Subleading operators and gamma5-scheme dependence in SMEFT for Higgs boson pair production

High Energy Physics - Phenomenology 2024-07-09 v1

Abstract

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 fusion is presented, in combination with NLO QCD corrections. Here we focus on the γ5\gamma_5-scheme dependence introduced by the four-top-quark-operators and the interplay with other operators contributing to this process in SMEFT.
