APACIC++ 1.0 A PArton Cascade In C++

Abstract
APACIC++ is a Monte Carlo event-generator dedicated for the simulation of electron–positron annihilations into jets. Within the framework of APACIC++, the emergence of jets is identified with the perturbative production of partons as governed by corresponding matrix elements. In addition to the build-in matrix elements describing the production of two and three jets, further programs can be linked allowing for the simultaneous treatment of higher numbers of jets. APACIC++ hosts a new approach...

Title of program: APACIC++, version 1.0
Catalogue Id: ADNE_v1_0

Nature of problem
With rising energies, the final state in high-energy electron positron-annihilations becomes increasingly complex. The number of jets as well as the number of observable particles, leptons, hadrons and photons, increases drastically and prevents any analytical prediction of the full final state. In addition, the transformation of the partons of perturbative quantum field theory into the experimentally observable hadrons is so far not understood on a quantitative level. Both obstacles prevent any ...

摘要
APACIC++ 是一款专用于模拟电子-正电子湮灭产生喷注过程的蒙特卡洛事件生成器（Monte Carlo event-generator）。在APACIC++的理论框架下，喷注的产生对应于由相应矩阵元（matrix elements）支配的部分子（partons）微扰产生过程。除内置的描述双喷注与三喷注产生的矩阵元外，还可接入额外程序以实现对更高多重数喷注的同步处理。APACIC++ 采用了全新的研究方法……

程序名称：APACIC++，版本1.0
目录编号：ADNE_v1_0

问题背景
随着能量不断提升，高能电子-正电子湮灭过程的末态愈发复杂。喷注数目以及可观测粒子（轻子、强子与光子）的数量均大幅增长，使得无法对完整末态做出解析预言。此外，微扰量子场论（perturbative quantum field theory）中的部分子向实验可观测强子的转化过程，目前仍未在定量层面得到清晰阐释。上述两大障碍阻碍了任何……
