Open full text 0 citations

Abstract

The ATLAS muon reconstruction has been improved for the Run-II of the LHC. In this presentation, we will discuss the new reconstruction algorithm and its latest performance measurements during the early run of the LHC in 2015 at $\\sqrt{s}= 13\\,$TeV using samples of $J/\\psi\\rightarrow \\mu\\mu$ and $Z\\rightarrow \\mu\\mu$ decays. The reconstruction efficiency, transverse momentum resolution and momentum scales measurements in the various regions of the detector and for muon momenta between 4 and hundreds of GeV are presented.
