Operator mixing, UV asymptotics of nonplanar/planar $2$ -point correlators, and nonperturbative large- $N$ expansion of QCD-like theories

Ugo Aglietti, Matteo Becchetti, Marco Bochicchio +2

We work out the interplay between lowest-order perturbative computations in the 't Hooft coupling, $g^{2} = g_{Y M}^{2} N$ , operator mixing, renormalization-group (RG) improved ultraviole…

Three-loop contributions to the $ρ$ parameter and iterated integrals of modular forms

Samuel Abreu, Matteo Becchetti, Claude Duhr +1

We compute fully analytic results for the three-loop diagrams involving two different massive quark flavours contributing to the $ρ$ parameter in the Standard Model. We find that t…

OPE and a low-energy theorem in QCD-like theories

Matteo Becchetti, Marco Bochicchio

We verify, both perturbatively and nonperturbatively asymptotically in the ultraviolet (UV), a special case of a low-energy theorem of the NSVZ type in QCD-like theories, recently…
