Abstract

We propose a simple method to simulate $W/Z$ + jet productions at hadron collisions. The simulation can be done by using existing tools with some modifications allowed to users. $W/Z$ + 1 jet events are generated using an ME-based event generator at the tree level. The divergence at low $p_{T}$ is suppressed by using the Sudakov form factor. PS is added with an appropriate consideration for PS-ME matching. The simulation for the $W$ + 1 jet production shows a smooth matching with the $W$ + 0 jet simulation at low $p_{T}$ s. The $Z$ + 1 jet simulation in the Tevatron Run I condition well reproduces the experimental measurement on the $p_{T}$ spectrum of $Z$ .
