Towards the discovery of new physics with lepton-universality ratios of $b\to s\ell \ell$ decays

Li-Sheng Geng, Benjamín Grinstein, Sebastian Jäger +3

Tests of lepton-universality as rate ratios in $b\to s\ell \ell$ transitions can be predicted very accurately in the Standard Model. The deficits with respect to expectations repor…
