GR@PPA_4b: A four bottom quark production event generator for pp/p p ̄ collisions

Abstract
We have developed an event generator, named GR@PPA_4b, for the four bottom quark (b b ̄ b b ̄ ) production processes at pp and p p ̄ collisions. The program implements all of the possible processes at the tree level within the framework of the Standard Model. Users can g...

Title of program: GR@PPA_4b (v1.0)
Catalogue Id: ADRH_v1_0

Nature of problem
Four bottom-quark production is an important channel for the study of Higgs-boson properties at future high energy hadron-collider experiments. However, the detectability is very ambiguous because only crude estimates based on many approximations have been available for background processes.

摘要
我们开发了一款名为GR@PPA_4b的事件生成器，用于质子-质子（pp）与质子-反质子（p$ar{p}$）对撞中四底夸克（$bar{b}bar{b}$）产生过程的模拟。本程序在标准模型（Standard Model）框架下实现了树级所有可能的产生过程。用户可……

程序名称：GR@PPA_4b（v1.0）
目录编号：ADRH_v1_0

问题性质
四底夸克产生过程是未来高能强子对撞机实验中研究希格斯玻色子（Higgs-boson）性质的重要产生道。但此前仅能通过多种近似得到背景过程的粗略估算，导致该过程的探测可行性始终模糊不清。
