Leptonic CP violation from a vector-like lepton
A. L. Cherchiglia, G. De Conto, C. C. Nishi
Leptonic CP violation is yet to be confirmed as an additional source of CP violation in fundamental interactions. We study the case where leptonic CP violation is spontaneous and i…
Two-loop gauge coupling -function in a four-dimensional framework: the Standard Model case
Adriano Cherchiglia
At present, the gauge coupling -function in the Standard Model (SM) is known up to four-loop order. As most SM calculations, dimensional regularization was employed. Despite its…
Two-loop Prediction of the Anomalous Magnetic Moment of the Muon in the Two-Higgs Doublet Model with GM2Calc 2
Peter Athron, Csaba Balazs, Adriano Cherchiglia +4
We present an extension of the GM2Calc software to calculate the muon anomalous magnetic moment () in the Two-Higgs Doublet Model. The Two-Higgs Doublet Model is…
A step towards a consistent treatment of chiral theories at higher loop order: the abelian case
Adriano Cherchiglia
As recently pointed out, regularization schemes defined in four-dimensions may also face inconsistencies in the presence of chiral fermions. In this work, we extend this analysis t…
A brief review of Implicit Regularization and its connection with the BPHZ theorem
Dafne Carolina Arias-Perdomo, Adriano Cherchiglia, Brigitte Hiller +1
Quantum Field Theory, as the keystone of particle physics, has allowed great insights to deciphering the core of Nature. Despite its striking success, by adhering to local interact…
Flavor constraints for a Vector-like quark of Nelson-Barr type
A. L. Cherchiglia, G. De Conto, C. C. Nishi
The Nelson-Barr (NB) mechanism to solve the strong CP problem assumes CP conservation, arranges vanishing at tree-level and requires vector-like quarks (VLQs) to transmit t…
