circe Version 1.02: beam spectra for simulating linear collider physics

Abstract
I describe parameterizations of realistic e±- and γ-beam spectra at future linear e^+ e^- -colliders. Emphasis is put on simplicity and reproducibility of the parameterizations, supporting reproducible physics simulations. The parameterizations are implemented in a library of distribution functions and event generators.

Title of program: circe Version 1.02
Catalogue Id: ADFI_v1_0

Nature of problem
Provide simple and reproducible, yet realistic, parameterizations of the e+- and gamma-beam spectra for linear colliders. The intricate beam dynamics in the interaction region of a high luminosity linear collider at sqrt(s)=500GeV result in non-trivial energy spectra of the scattering electrons, positrons and photons. Physics simulations require simple and reproducible, yet realistic, parameterizations of these spectra.

摘要：本文针对未来直线正负电子对撞机（linear e⁺e⁻ collider）的真实正负电子束与伽马光子束（γ-beam）能谱，给出参数化建模方案。本研究重点关注参数化过程的简洁性与可复现性，以支撑可复现的物理模拟工作。该参数化方法已集成于分布函数与事件生成器库中。

问题本质：为直线对撞机的正负电子束与伽马光子束能谱提供简洁可复现且贴合真实场景的参数化建模方案。在质心系能量√s=500GeV的高亮度直线对撞机相互作用区域内，复杂的束流动力学过程会使散射电子、正电子与光子产生非平庸的能谱分布。物理模拟工作亟需这类兼具简洁性、可复现性与真实性的能谱参数化方法。
