Description
Below the electroweak scale, the LEFT provides a systematic approximation of both heavy SM and BSM physics. When extending the LEFT to next-to-leading-log accuracy, a number of technical challenges arise. In this talk, I will discuss the basis construction in the 't Hooft-Veltman scheme, $\gamma_5$ and evanescent operators, the restoration of chiral symmetry, and the role of redundant operators in the cancellation of subdivergences.
