摘要：

简要回顾了GR@PPA事件发生器的历史和现状。GR@PPA的发展始于2000年，目的是为强子碰撞相互作用提供一个NLO事件发生器框架。在2002年第一次发布支持四个底夸克产生过程的包（GR @ PPA\_4b）之后，许多多粒子产生过程被添加到包中：2004年的GR@PPA\_ALL和2006年的GR@PPA 2.7。现在我们将发布一个新的软件包（GR@PPA 2.8），它支持带有初始态喷流匹配的单弱玻色子和双弱玻色子产生过程。虽然目前包含的矩阵元素仍处于树级，但这个新版本是构建一致的NLO事件生成器的重要一步。

英文摘要：

The history and the present status of the GR@PPA event generator are briefly reviewed. The development of GR@PPA started in 2000 in order to provide a framework of NLO event generators for hadron collision interactions. After the first release of the package (GR@PPA\_4b) in 2002, which supported four bottom quark production processes, many multi-particle production processes have been added to the package: GR@PPA\_ALL in 2004 and GR@PPA 2.7 in 2006. Now we are going to release a new package (GR@PPA 2.8), which supports single and double weak-boson production processes with an initial-state jet matching. Though the matrix elements presently included are still at the tree level, this new release is an important step towards constructing consistent NLO event generators.
