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…

Z and Higgs Factory Implications of Two Higgs Doublets with First-Order Phase Transitions
Anisha, Francisco Arco, Stefano Di Noi +2
We investigate the potential of future electron-positron colliders, such as FCC-ee and CEPC, to probe 2-Higgs-doublet models (2HDMs) that facilitate a strong first-order electrowea…

Mapping between schemes in the Standard Model Effective Field Theory
S. Di Noi, R. Gröber, P. Olgoso
We explore the relation between two distinct prescriptions for in dimensional regularization -- the Breitenlohner Maison t'Hooft Veltman (BMHV) scheme and Naive Dimensional R…
