We present a new version of PyR@TE, a Python tool for the computation of renormalization group equations for general, non-supersymmetric gauge theories. Its new core relies on a recent paper by Poole & Thomsen (arXiv:1906.04625) to compute the $\beta

Comments on gauge anomalies at dimension-six in the Standard Model Effective Field Theory

Autor: Bonnefoy, Quentin, Di Luzio, Luca, Grojean, Christophe, Paul, Ayan, Rossia, Alejo N.

We question the use of triangle diagrams in the broken phase of the Standard Model Effective Field Theory (SMEFT) to derive sum-rules on certain dimension-six coefficients, as recently put forward by Cata, Kilian and Kreher in Ref. [arXiv:2011.09976]

We study whether higher-dimensional operators in effective field theories, in particular in the Standard Model Effective Field Theory (SMEFT), can source gauge anomali

Three-loop Euler-Heisenberg Lagrangian in 1+1 QED, part 1: single fermion-loop part

Autor: Huet, Idrish, Rausch De Traubenberg, Michel, Schubert, Christian

Publikováno v: JHEP
JHEP, 2019, 03, pp.167. ⟨10.1007/JHEP03(2019)167⟩

We study the three-loop Euler-Heisenberg Lagrangian in spinor quantum electrodynamics in 1+1 dimensions. In this first part we calculate the one-fermion-loop contribution, applying both standard Feynman diagrams and the worldline formalism which lead
