Abstract

We construct an event generator for ppΒ»W+Xe+X including complete O(s) corrections, and interface with initial- and final-state parton showers. Problems with negative weights and with double counting higher-order parton radiation are averted. We present results for W+n-jet production, and compare with results from complete tree-level calculations, and shower calculations off of the lowest-order 2 2 subprocess. Our approach gives the correct total cross section through O(s) and proper high-qT(W) distribution.
