The Atlas Muon Trigger Interface (muctpi)
At LHC interesting physics in many cases will be indicated by the presence of muons in an event[1]. Examples are searches for new heavy particles with muons among the decay products. A muon with high pT could indicate such a decay. Another interesting topic to be investigated at LHC is the search for rare B-meson decays. The branching ratio for the decay B0 -> μμ is predicted to be of the order...
متن کاملTrigger 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 ...
متن کاملLatest Results on RPCs for the ATLAS LVL1 Muon Trigger
The performances of 3, 2 and 1.5 mm gap RPCs operated with a heavy, environmentally safe industrial gas, C 2 H 2 F 4 , have been tested at cosmic ray fluxes. Emphasis is given to the study of avalanche-to-streamer transition. ( 1998 Elsevier Science B.V. All rights reserved. Resistive Plate Chambers will be used as the LVL1 muon trigger detector in the barrel region (DgD(1) of the ATLAS experim...
متن کاملPerformance of the ATLAS Muon Trigger in Run I and Upgrades for Run II
The ATLAS experiment at the Large Hadron Collider (LHC) has taken data at a centre-of-mass energy between 900 GeV and 8 TeV during Run I (2009-2013). The LHC delivered an integrated luminosity of about 20 fb−1 in 2012, which required dedicated strategies to ensure the highest possible physics output while effectively reducing the event rate. The Muon High Level Trigger has successfully adapted ...
متن کاملIn-situ Determination of the ATLAS Muon Performance
The ATLAS detector allows for the precise and efficient reconstruction of muons. Muon tracks are reconstructed with 97% efficiency with a momentum resolution of approximately 2-3% over most of the kinematic range and better than 10% for transverse momenta up to 1 TeV and |η | <2.7. We present methods to measure the performance of the muon identification during the operation of the ATLAS detecto...
