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