LHC physics: the first one--two year(s)

Abstract

We discuss the strategy to commission the LHC experiments and understand standard physics at sqrt{s}=14TeV before data taking starts and in the early phases of the LHC operation. In particular, we review the various steps needed to understand and calibrate the ATLAS and CMS detectors, from construction quality checks, to beam tests, to cosmics runs, to first collisions. We also review the preparation and tuning of Monte Carlo tools, and present a few examples of physics goals for integrated luminosities of up to a few inverse fb.Comment: Proceedings of the 2nd Italian Workshop on the physics of Atlas and CM
