Implementation and performance of the ATLAS Trigger Muon "Vertical Slice"

Mostrar otras versiones (1)

The ATLAS (A Toroidal LHC ApparatuS) trigger system is designed to keep high effiency for interesting events while achieving a rejection of low transverse momentum (p_T) physics of about 10^7, thus reaching the ~200Hz data storage capability of the Data Aquisition system. A three levels structure ha...

Descripción
Sumario:The ATLAS (A Toroidal LHC ApparatuS) trigger system is designed to keep high effiency for interesting events while achieving a rejection of low transverse momentum (p_T) physics of about 10^7, thus reaching the ~200Hz data storage capability of the Data Aquisition system. A three levels structure has been implemented for this purpose, as described in this work for the case of the muon trigger system. After describing the implementation, some performance results are presented in terms of final trigger rates, resolutions, efficiencies, background rejection and algorithm latency.
