2016 and 2017 data-taking periods. For the [$\Pe\tauh$]{}final state, the trigger relies on the presence of an isolated electron satisfying stringent identification criteria and passing $\pt>25$ or $>$35in 2016 and 2017 data, respectively. For the [$\PGm\tauh$]{}final state, the trigger is based on the presence of an isolated muon with $\pt>24$ and $>$27in 2016 and 2017 data, respectively. Trigger efficiencies are measured in data and simulation. In addition to corrections mentioned in Section \[sec:evtreco\], we apply scale factors to the simulation to account for any discrepancies in trigger efficiency with data. These scale factors are parameterized in the and $\eta$ of the reconstructed electron, muon, or candidates, or the reconstructed for events selected using triggers.

Beyond the trigger selection, the baseline event selection for the [$\tauh\tauh$]{}analysis requires the presence of exactly two isolated candidates of opposite charge, satisfying the DeepPF selection described in Section \[sec:evtreco\], with $\abs{\eta}<2.3$ and $\pt > 40$ and $>$45in the 2016 and 2017 analysis, respectively, as well as no additional candidates with $\pt > 30\GeV$ satisfying the very loose working point of the MVA-based discriminant. We veto events with additional electrons or muons with $\pt>20\GeV$
