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…
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…
May the four be with you: Novel IR-subtraction methods to tackle NNLO calculations
W. J. Torres Bobadilla, G. F. R. Sborlini, P. Banerjee +21
In this report, we present a discussion about different frameworks to perform precise higher-order computations for high-energy physics. These approaches implement novel strategies…
Consequences of vector-like quarks of Nelson-Barr type
A. L. Cherchiglia, C. C. Nishi
The Nelson-Barr mechanism to solve the strong CP problem requires vector-like quarks (VLQs) to transmit the spontaneous CP breaking to the SM. We study the scenario where only thes…
Solving the strong CP problem with non-conventional CP
A. L. Cherchiglia, C. C. Nishi
A very simple model is presented where all CP violation in Nature is spontaneous in origin. The CKM phase is generated unsuppressed and the strong CP problem is solved with only mo…
Supercurrent anomaly and gauge invariance in N=1 supersymmetric Yang-Mills theory
Y. R. Batista, Brigitte Hiller, Adriano Cherchiglia +1
We analyse Feynman diagram calculational issues related to the quantum breaking of supercurrent conservation in a supersymmetric non-abelian Yang-Mills theory. For the sake of simp…
