General analyses of B-physics processes beyond the Standard Model require accounting for operator mixing in the renormalization-group evolution from the matching scale down to the typical scale of B physics. For this purpose the anomalous dimensions of the full set of local dimension-six operators beyond the Standard Model are needed. We present here for the first time a complete and non-redundant set of dimension-six operators relevant for B-meson mixing and decay, together with the complete one-loop anomalous dimensions in QCD and QED. These results are an important step towards the automation of general New Physics analyses.

At the level of accuracy reached by such computations, electroweak corrections both in the SM and in NP scenarios can also be included and may prove important [27,28]. Moreover, this framework can be easily extended to include NP eects. These will lead either ”

In contrast to the discussion in WET at the b-quark scale, more Wilson coecients become relevant in SMEFT due to RG mixing above [71{73] and below [74,75] the EW scale. Due to the pattern of Wilson coecients preferred by the global t, we focus on S”
