Title: | Performance of the ATLAS muon trigger in pp collisions at √s = 8 TeV | Authors: | Santos, S. P. Amor dos Carvalho, J. Fiolhais, M. C. N. Galhardo, B. Veloso, F. Wolters, H. ATLAS Collaboration |
Issue Date: | 2015 | Publisher: | Springer Nature | Serial title, monograph or event: | European Physical Journal C | Volume: | 75 | Issue: | 3 | Abstract: | The performance of the ATLAS muon trigger system is evaluated with proton–proton collision data collected in 2012 at the Large Hadron Collider at a centre-of-mass energy of 8TeV. It is primarily evaluated using events containing a pair of muons from the decay of Z bosons. The efficiency of the single-muon trigger is measured for muons with transverse momentum 25 < pT < 100GeV, with a statistical uncertainty of less than 0.01% and a systematic uncertainty of 0.6%. The pT range for efficiency determination is extended by using muons from decays of J/ψ mesons, W bosons, and top quarks. The muon trigger shows highly uniform and stable performance. The performance is compared to the prediction of a detailed simulation. | URI: | https://hdl.handle.net/10316/109117 | DOI: | 10.1140/epjc/s10052-015-3325-9 | Rights: | openAccess |
