Симпатичная статейка от Зураба Силагадзе

Используется т.наз. метод спиральных амплитуд (надо бы разобраться, что это такое!).

MUMUG: a fast Monte Carlo generator for the process e+e−→μ+μ−γ: https://arxiv.org/abs/2010.15553
Z.K. Silagadze
A fast leading-order Monte Carlo generator for the process e+e−→μ+μ−γ is described. 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.
