优雅--弹性事件generator
Elegent -- an elastic event generator
摘要：
虽然核子的弹性散射看起来像是一个简单的过程，但它对理论提出了长期的挑战。由于缺少硬能标，微扰QCD不能应用。相反，出现了许多现象学/理论模型。在本文中，我们提出了一个C++库中的一些最突出的模型的统一实现，此外，扩展到占电磁相互作用的影响。该图书馆还配备了一些实用程序。例如，程序可以对四个动量传递平方t、碰撞参量b和碰撞能量sqrt（s）中的许多感兴趣的分布进行采样。这些分布在ISR，SppS，RHIC，Tevatron和LHC能量可从项目网站下载。以ROOT文件和PDF数字的形式提供模型之间的比较。该软件包还包括一个工具，用于弹性散射事件的蒙特卡罗生成，它可以很容易地嵌入到任何其他程序框架。
英文摘要：
Although elastic scattering of nucleons may look like a simple process, it presents a long-lasting challenge for theory. Due to missing hard energy scale, the perturbative QCD can not be applied. Instead, many phenomenological/theoretical models have emerged. In this paper we present a unified implementation of some of the most prominent models in a C++ library, moreover extended to account for effects of the electromagnetic interaction. The library is complemented with a number of utilities. For instance, programs to sample many distributions of interest in four-momentum transfer squared, t, impact parameter, b, and collision energy sqrt(s). These distributions at ISR, SppS, RHIC, Tevatron and LHC energies are available for download from the project web site. Both in the form of ROOT files and PDF figures providing comparisons among the models. The package includes also a tool for Monte-Carlo generation of elastic scattering events, which can easily be embedded in any other program framework.
