We study implications of the four-fermion semileptonic operators at the low-energy and at electroweak (EW) scale in the framework of Standard Model Effective Field Theory (SMEFT). We show how the renormalization group (RG) running effects can play a key role in probing the generic flavour structure of such operators. It is shown that at the 1loop level, through RG running, depending upon the flavour structure these operators can give rise to sizable effects at low energy in the electroweak… Expand

Revisiting Lepton Flavor Universality in B Decays.
The low-energy effective Lagrangian is constructed taking into account the running effects from Λ down to v through the one-loop renormalization group equations (RGEs) in the limit of exact electroweak symmetry and QED RGEs from v down to the 1 GeV scale. Expand
Effective lagrangian analysis of new interactions and flavour conservation
