Acknowledgments We congratulate our colleagues in the CERN accelerator departments for the excellent performance of the LHC machine. We thank all contributors to the LHC Luminosity Calibration and Monitoring Working Group and, in particular, its co-coordinator  Witold Kozanecki  for the discussions on beam instrumentation and beam physics. We also thank the technical and administrative staffs at  CERN  and at other  CMS institutes  for their contributions to the success of the CMS effort. In addition, we gratefully acknowledge the computing c enters and personnel of the Worldwide LHC Computing Grid and other centers for delivering so effectively the computing infrastructure essential to our analyses.
