Monte Carlo and large angle gluon radiation

摘要:

我们讨论的问题,将反冲效应纳入概率QCD演化方案的基础上的图片的颜色偶极子在最近的Monte Carlo程序。这样的方案正确地描述了子领导软贡献多重分布。然而,我们发现,一个简单的接收纳入反冲效应的偶极倍增图片冲突的共线因式分解,并没有导致正确的DGstrom方程。

英文摘要:

We discuss the problem of incorporating recoil effects into the probabilistic QCD evolution scheme based on the picture of colour dipoles as done in recent Monte Carlo programs. Such a scheme correctly describes subleading soft contributions to multiplicity distributions. However we find that a simple receipt for incorporating recoil effects into the dipole multiplication picture conflicts the collinear factorization and does not lead to the correct DGLAP equation.
