Query: MUMUG: a fast Monte Carlo generator for radiative muon pair production
  (a pedagogical tutorial)   A fast leading-order Monte Carlo generator for the process
$e^+e^-\to\mu^+\mu^-\gamma$ is described. In fact, using the
$e^+e^-\to\mu^+\mu^-\gamma $ process as an example, we provide a pedagogical
demonstration of how a Monte Carlo generator can be created from scratch. The
$e^+ e^- \to \mu^+ \mu^- \gamma$ process was chosen, since in this case we are
not faced with either too trivial or too difficult a task. Matrix elements are
calculated using the helicity amplitude method. Monte Carlo algorithm uses the
acceptance-rejection method with an appropriately chosen simplified
distribution that can be generated using an efficient algorithm. We provide a
detailed pedagogical exposition of both the helicity amplitude method and the
Monte Carlo technique, which we hope will be useful for high energy physics
students.
