Abstract [en]

At the high luminosity LHC the current L1 trigger of ATLAS will not be able to reduce the number of events to a level accepted by the higher level triggers. It is therefore of importance to implement new strategies of triggering to be able to continue successful operation. This study examined an RoI-seeded muon track trigger in the Higgs to tau-tau to mu-mu channel and found that the ability to select signal events was very good, even at five times rejection of soft minimum bias events compared to the current trigger. The overall trigger efficiency for selected signal muons is decreased by less than 4% with smearing of track transverse momenta up to ten times coarser than the current offline resolution.
