A measurement of the muon reconstruction efficiency in 2010 ATLAS data using jpsi decays
A measurement of the ATLAS muon reconstruction efficiency based on the {\it tag-and-probe} method using muons from decays of $\jpsi$ mesons is presented. The data sample, corresponding to 40~\ipb\ of \textit{pp} collisions data at $\sqrt {s} = 7$~\TeV, was collected during the 2010 run. These result...

| Sumario: | A measurement of the ATLAS muon reconstruction efficiency based on the {\it tag-and-probe} method using muons from decays of $\jpsi$ mesons is presented. The data sample, corresponding to 40~\ipb\ of \textit{pp} collisions data at $\sqrt {s} = 7$~\TeV, was collected during the 2010 run. These results improve the previous determination of the reconstruction efficiency at low transverse momenta thanks to a better statistical precision and to lower systematic uncertainties. |
