Trigger logic of the ATLAS First Level Muon Trigger

We present the design of the first level muon trigger in the central toroid of the ATLAS experiment at the Large Hadron Collider (LHC). The trigger is based on fast, finely segmented gaseous detector, Resistive Plate Chambers (RPC), to unambigously identify the interaction bunch crossing and to provide a sharp threshold over a large interval of transverse momentum. We describe the logic scheme ...

The CMS trigger system

This paper presents an overall description of the CMS trigger system which is composed by the Level-1 Trigger and the High-Level Trigger subsystems. Details on the algorithms and selection criteria at a luminosity of 2x10 33 cm-2 s-1 are provided. High efficiencies for benchmark physics channels are attainable with an inclusive selection that avoids detailed topological requirements on the event.
