to the total transverse momentum of the system of SUSY particles. This reweighting procedure is based on studies of the of bosons [@Chatrchyan:2013xna]. The signal production cross sections are calculated at NLO using next-to-leading logarithmic (NLL) soft-gluon resummations [@Fuks:2013lya]. The most precise calculated cross sections available are used to normalize the simulated SM background samples, often corresponding to next-to-next-to-leading order accuracy.

Event selection {#sec:evtsel}
===============

The search strategy in the [$\tauh\tauh$]{}final state relies on a cut-and-count analysis based on the SRs described below in Section \[sec:tautausel\], while for the [$\ell\tauh$]{}final states we make use of BDTs to discriminate between signal and background as described in Section \[sec:leptausel\]. The data used in this search are selected through triggers that require the presence of isolated electrons, muons, candidates, or . The data used for the [$\tauh\tauh$]{}analysis are collected with two sets of triggers. Events with $\ptmiss < 200$are selected using a trigger that requires the presence of two candidates, each with $\pt>35$ and $>$40in 2016 and 2017 data, respectively. We gain up to 7% additional signal efficiency for events with $\ptmiss>200$with the help of a trigger that requires the presence of substantial , with a threshold varying between 100 and 140during the
