Precision Measurements at the LHC

In addition to the large discovery potential for Higgs bosons and new physics phenomena, like for instance Supersymmetry, experiments at the LHC will also be able to perform precise measurements of many Standard Model processes. The huge cross sections and the high collision energy will allow the exploration of less well tested areas of the Standard Model and to improve significantly on the precision of many parameters. Therefore the detailed experimental study of known Standard Model processes at the LHC will not only prepare the anticipated discoveries but also complement their interpretation. This article describes some selected items on the perspectives of the two general purpose detectors ATLAS and CMS on the determination of parton distribution functions, tests of QCD and electroweak physics at the highest energies and the physics of the top quark.
