The LFU ratio [Formula: see text] in the Standard Model and beyond

We discuss the possibility of performing precise tests of [Formula: see text] universality in [Formula: see text] decays. We show that in wide regions of the dilepton invariant mass spectrum the ratio between muonic and electronic decay widths can be predicted with high accuracy, both within and bey...
