Where eff_t_AX refers to the trigger efficiency associated to each intermediate chain and each final decay of the bino (for example eff_t_Ia correspond to the trigger efficiency when the binos are produced through the channel I and decay to electrons and neutrinos) and eff_sel_x correspond to the selection efficiency of the displaced binos for the decay channel x.

Excluded scenarios with short-lived Bino LSP
*******************************************
The exclusion for this points is based on the search 1908.08215 'Search for electroweak production of charginos and sleptons decaying into final states with two leptons and missing transverse momentum in s√=13 TeV pp collisions using the ATLAS detector', where we assume that non-prompt decays of the bino are not displaced enough to be detected in LLP searches, bu displaced enough to be discarded as cosmic rays background in prompt searches. Under this assumption we could compare the processes:
