was not very conservative. Similarly, it shows that our result does not rely on the exact shape of the high ${p_\text{T}}$ tail of the distribution in the right panel of figure \[fig:dimu\].

To realize this optimized ${p_\text{T}}$-cut in an experimental analysis, one could choose the value of ${p_\text{T}}^\text{min}$ corresponding to the stau mass that—for example, according to figure \[fig:lum-num-mass-run\]—is within reach at the luminosity of the analyzed dataset.

Direct production versus other channels {#sec:production}
=======================================

The cross section for the production of superparticles heavier than the stau can be larger than the DY cross section considered so far. Such sparticles promptly decay into the NLSP, emitting Standard Model (SM) particles which provide an additional signature with potentially higher significance than the detection of the metastable stau. However, the SM particle radiation from cascade decays depends strongly on the sparticle mass spectrum and has to be distinguished from a higher SM background. Hence, we assume that the easiest way to find SUSY in the considered scenario is the direct detection of the NLSP, independently of its production channel. Then we can estimate whether staus from direct production or those from decays of heavier sparticles will be the dominant contribution to the
