Christoph Gnendiger,Adrian Signer,Adrian Signer,Dominik Stöckinger,Alessandro Broggio,A. L. Cherchiglia,Félix Driencourt-Mangin,A. R. Fazio,Brigitte Hiller,Pierpaolo Mastrolia,Tiziano Peraro,Roberto Pittau,Giovanni Marco Pruna,German Rodrigo,Marcos Sampaio,German F. R. Sborlini,German F. R. Sborlini,W. J. Torres Bobadilla,W. J.

TL;DR: In this paper, several regularization schemes for ultraviolet and infrared singularities appearing in higher-order computations in quantum field theories are presented. But the similarity and differences between them are not discussed.
Journal ArticleDOI
Chiral anomaly and CPT invariance in an implicit momentum space regularization framework
TL;DR: In this article, a momentum space framework is proposed to treat field-theoretical infinities in perturbative calculations when parity-violating objects occur. But the framework does not handle the subtleties involved when a radiative correction is finite.
Journal ArticleDOI
Gauge invariance and the CPT and Lorentz violating induced Chern-Simons-like term in extended QED
TL;DR: In this paper, the authors considered the preservation of gauge symmetry at higher orders in the background vector b = b − ε − μ when radiative corrections are considered and showed that even parity sectors of the complete vacuum polarization tensor must be preserved by quantum corrections.
Journal ArticleDOI

TL;DR: In this paper, the authors report the outcome of the topical workshop: paving the way to alternative NNLO strategies (https://indico.ific.u.es/e/WorkStop-ThinkStart_3.0), by presenting a discussion about different frameworks to perform precise higher-order computations for high-energy physics.
Journal ArticleDOI
Multi-quark interactions with a globally stable vacuum
TL;DR: In this paper, it was shown that U ( 3 ) L × U( 3 ) R 8-quark interactions stabilize the asymmetric ground state of the well-known model with four-quarks Nambu-Jona-Lasinio and six-quars 't Hooft interactions.
