A number of extensions of the Standard Model (SM) result in particles that are neutral, weakly-coupled and have macroscopic decay lengths that can be
comparable with ATLAS detector dimensions. For the purpose of exploring the challenges to the trigger posed by long-lived neutral particles, the Hidden
Valley scenario serves as an excellent setting. The goal of this study is to obtain benchmark triggers for processes with such non-standard signatures using
MonteCarlo simulated events in the ATLAS appartus.

Period: June-July or September-November. No August.
