Abstract: In this note, we present the results of sensitivity studies on the lepton universality in the channel ϒ(nS) → 𝓵𝓵 via initial-state radiation (ISR). The study is performed with Phase III Monte Carlo samples and cover an integrated luminosity range up to the design value of 50 ab−1. This work show that the even with the complete design dataset the statistical uncertainty is not reduced enough to have a competitive measurement.
