GR @ PPA 2.8.3更新
GR@PPA 2.8.3 update
摘要：
GR@PPA 2.8是一个包含强子碰撞中单、双弱玻色子产生过程事件发生器的程序包，其中采用喷注匹配方法模拟了整个相空间中的弱玻色子运动学。自2010年11月首次发布以来，已对程序组件进行了多项改进。本报告描述了到目前为止应用的改进和更改，直到2.8.3版本。
英文摘要：
GR@PPA 2.8 is a program package including event generators for single and double weak-boson production processes at hadron collisions, in which a jet matching method is implemented for simulating the weak-boson kinematics in the entire phase space. Since the initial release in November, 2010, several improvements have been applied to the program components. This report describes the improvements and changes applied so far, up to the 2.8.3 release.
