$n\sigma^{\textrm{TPC}}_{e^\pm}$ distribution without (black) and with (green) \gls{EMCal} electron identification cuts of $E/p$ and $\shshlo$. Electrons form a Gaussian distribution centered around zero, indicated by the gray dashed line. The signal and background selection windows considered for the following $E/p$ plots are indicated by the red and blue shaded area, respectively. The distributions are shown for various event triggers in \pp\ collisions at \sthirteen\ in different \pT\ intervals.
