Latunde-Dada, O., Gieseke, S., & Webber, B. R. (2006). A Positive-Weight Next-to-Leading-Order Monte Carlo for e+ e- Annihilation to Hadrons..
We apply the positive-weight Monte Carlo method of Nason for simulating QCD processes accurate to Next-To-Leading Order to the case of e+e− annihilation to hadrons. The method entails the generation of the hardest gluon emission first and then subsequently adding a ‘truncated’ shower before the emission. We have interfaced our result to the Herwig++ shower Monte Carlo program and obtained better results than those obtained with Herwig++ at leading order with a matrix element correction.
