Trigger systems at hadron super-colliders

This paper discusses the techniques used in state-of-the-art trigger systems, such as those currently under development for experiments at the Large Hadron Collider (LHC), and describes the new challenges that would have to be faced in a super-collider operating at very high energy and luminosity. In particular, it addresses the case of an upgraded LHC with very high luminosity and a short bunch-crossing interval.
