EARLY-DATA ANALYSIS: J/Y IN DI-MUONS The first LHC run period in 2009-2010 is expected to deliver an integrated luminosity of the order of 100 pb-1 with the following schedule: first collisions during the first week of December with a CM energy of √s = 900GeV; √s = 2.2 TeV untill the end of 2009; √s = 7 TeV in 2010. Given the Standard Model predictions, ATLAS is expected to detect: J/Y  + ≈ 500/ pb-1 , at √s = 900 GeV J/Y  + ≈ 6000/ pb-1 , at √s = 7 TeV Z  + /pb-1 ≈ 200/ pb-1 , at √s = 7 TeV THE STUDY OF THESE SAMPLES HAS A DOUBLE ADVANTAGE, BECAUSE IT ALLOWS TO TEST DETECTOR CALIBRATION AND PERFORMANCE AND TO MAKE FIRST CROSS SECTION MEASUREMENTS: First pb-1  detector and trigger understanding and calibration; First 5pb-1  trigger and offline muon efficiency studies; >10 pb-1  J/Y cross section measurement;
