sensitivity by up to 50%, where the figure of merit considered is the 95% upper limit on the cross section for pair production obtained with the data collected in 2016. The improvement is less significant than expected, since it is found that the estimated signal acceptance is reduced when the fast detector simulation that was previously used to model signal events is replaced in this search with the more realistic, full -based detector simulation [@geant4]. Differences in the signal acceptance for the fast and more accurate full detector simulations are mainly caused by differences in the reconstructed visible transverse momentum (), which is found to have larger values in the case of the fast simulation.

We consider the superpartners of both left- and right-handed leptons, [$\PSGt_{\mathrm{L}}$]{}and [$\PSGt_{\mathrm{R}}$]{}. The cross section for [$\PSGt_{\mathrm{L}}$]{}pair production is expected to be about a factor of three larger than for [$\PSGt_{\mathrm{R}}$]{}pairs [@Fuks:2013lya]. The experimental acceptance is also expected to be different for left- and right-handed assignments because of the differences in the polarization of the leptons produced in [$\PSGt_{\mathrm{L}}$]{}and [$\PSGt_{\mathrm{R}}$]{}decays. The decay products of hadronically and leptonically decaying leptons originating from [$\PSGt_{\mathrm{R}}$]{}decays are predicted to have larger and smaller , respectively, than those originating from
