论文摘要
最近，需要一个易于使用且通用的基本粒子腐烂的通用事件发生器或具有更高多重性（$ n> 2 $）状态的强化状态（$ n> 2 $）。我们介绍了这种库的结构，以产生生成衰减过程的运动学的发电机，并可用于整合该衰减相位空间上的任何矩阵元素。提出了一些测试示例，并将结果与文献中知道的结果进行了比较。作为一个例子之一，我们将标准模型Higgs玻色子腐烂成四个瘦素。这里讨论的发电机与根接口兼容。
Recently, there is a need for a general-purpose event generator of decays of an elementary particle or a hadron to a state of higher multiplicity ($N > 2$) that is simple to use and universal. We present the structure of such a library to produce generators that generate kinematics of decay processes and can be used to integrate any matrix element squared over phase space of this decay. Some test examples are presented, and results are compared with results known from the literature. As one of examples we consider the Standard Model Higgs boson decay into four leptons. The generators discussed here are compatible with the ROOT interface.
