Abstract: We present a collection of selected results on the performance of Belle II in the identification of electrons and muons. This work is carried out using data collected at the Belle II experiment from 2019 to mid-2021. The dataset corresponds to a total integrated luminosity of $\int L~\mathrm{dt} = 190 \invfb$ collected at the centre-of-mass energy of the $\Upsilon(4S)$, with an additional sample corresponding to $\int L~\mathrm{dt} = 18 \invfb$ of off-resonance data collected over the same period.

The record appears in these collections:
