The efficiencies of the triggers for selecting displaced decays as a function of the decay position are presented for simulated events. The effect of pile-up interactions on the trigger efficiencies and the dependence of the trigger rate on instantaneous luminosity during the 2012 data-taking period at the LHC are discussed.en500 - Science::530 - Physicsarticle10.7892/boris.584391305.2284v200032257290002610.1088/1748-0221/8/07/P07015
