Description
We motivate a measurement of various ratios of W and Z cross sections at the Large Hadron Collider at large values of the boson transverse momentum. We study the dependence of predictions for these cross-section ratios on the multiplicity of associated jets and the boson pT . We present a detailed study of the flavour decomposition of the initial-state partons and an evaluation of the theoretical uncertainties. We show that a precise measurement will be useful in validating theoretical predictions needed in data-driven methods to estimate backgrounds in searches for new physics and also to constrain Parton Distribution Functions.
