Muon momentum scale and resolution in pp collisions at $\sqrt{s}$ = 8 TeV in ATLAS

This work shows the performance in the muon momentum scale and resolution achieved by ATLAS during the 2012 run at $\sqrt{s} = 8$. The momentum scale is known with an uncertainty ranging from 0.05\% (in the central rapidity region) to 0.2\% (at large rapidities). The muon momentum resolution is measured to be 1.7\% for central muons with low momentum ($p_T\simeq10$ GeV) and reaches 4\% for high-$p_T$ muons in the forward regions of the ATLAS detector.
