Query: Unweighted event generation in hadronic WZ production at order(alpha_S)   We present an algorithm for unweighted event generation in the partonic
process pp -> WZ (j) with leptonic decays at next-to-leading order in alpha_S.
Monte Carlo programs for processes such as this frequently generate events with
negative weights in certain regions of phase space. For simulations of
experimental data one would like to have unweighted events only. We demonstrate
how the phase space from the matrix elements can be combined to achieve
unweighted event generation using a second stage Monte Carlo integration over a
volume of real emissions (jets). Observable quantities are kept fixed in the
laboratory frame throughout the integration. The algorithm is applicable to a
broader class of processes and is CPU intensive.
