W physics at the LHC with FEWZ 2.1

Abstract We present an updated version of the FEWZ (Fully Exclusive W and Z production) code for the calculation of ^(W±)and ^(γ*)Z production at next-to-next-to-leading order in the strong coupling. Several new features and observables are introduced, and an order-of-magnitude speed improvement over the performance of FEWZ 2.0 is demonstrated. New phenomenological results for ^(W±)production and comparisons with LHC data are presented, and used to illustrate the range of physics studies possi...
