Physics potential of precision measurements of the LHC luminosity
arXiv:1203.5633
Abstract
A precision measurement of the LHC luminosity is a key ingredient for its physics program. In this contribution first of all we review the theoretical accuracy in the computation of LHC benchmark processes. Then we discuss the impact of available and future LHC data in global analysis of parton distributions, with emphasis on the treatment of normalization uncertainties. Finally we present some suggestions for the physics opportunities that can become available by measuring ratios of cross sections between the 8 TeV and 7 TeV runs.
