65. Two-loop anomalous dimensions in the Low-Energy EFT

Javier Virto (Universitat de Barcelona)

I will discuss a few issues related to anomalous dimensions of the EFT below the EW scale at two loop order.

4. Evanescent schemes and prescriptions

Marko Pesut (University of Zürich)

03/06/2025, 12:00

In Effective Field Theories, evanescent operators are introduced to compensate for the breakdown of four-dimensional Dirac identities (e.g. Fierz Identities) when used in combination with dimensional regularization.

In this talk, we provide an alternative approach where contributions of evanescent operators are viewed as corrections to d=4 Dirac relations. This new perspective not only...

11. t'Hooft-Veltman Scheme in the Functional Approach

Mr ADRIÁN Moreno Sánchez (Universidad de Granada)

03/06/2025, 12:20

The 't Hooft-Veltman scheme is the only consistent prescription for handling γ5γ5​ at all orders in the perturbative expansion, which is crucial for multi-loop computations. However, its application within EFT frameworks has been limited due to technical challenges.

In this talk, we will explore a practical approach to implementing this regularization scheme using functional methods. This...
