A comparison of trigger efficiencies for DT, CSC and RPC triggers using W→μν sample

Muons are expected to provide clean signature for a wide range of physics processes. In addition to identify the muons and the precise measurement of their momentum, muons system provides fast information of triggering-a challenging problem at LHC. There are two sets of muon detectors: wire chambers (drift tubes and cathode strip chambers) and resistive plate chambers. At the L1 trigger, two systems are completely independent and can run in standalone mode. This work presents the trigger efficiencies and comparison for all these three types of triggers using the sample W→μν. The Resistive Plate Chambers (RPC), Drift Tubes (DT) and Cathode Strip Chambers (CSC) geometry version implemented in new CMSSW releases have been used.
