ATLAS measurements of $J/\psi$ events at $\sqrt{s} = 7 TeV$
The first J/psi to mu+ mu- observation using the ATLAS detector, in 7 TeV proton-proton collisions at the LHC, is reported for an integrated luminosity of approximately 6.4 nb-1. The reconstructed invariant mass agrees with the PDG value within statistical uncertainties, and the peak width is compat...
