论文摘要
在本文中，我们提出了一种新的Monte Carlo事件生成器肾上腺，以模拟电子脉冲凸线的过程。在发电机的当前版本中，实现了Bhabha散射（$ e^+e^ - \ to e^-e^+$）和higgs-strahlung（$ e^+e^ - \ to zh $）过程。基于SANC（支持山脉实验的分析和数字计算）模块，新发生器考虑了完整的一环和一些具有有限粒子质量和极化的高阶电子辐射校正。新的发电机在共线区和$ ZH $生产阈值有效运行。它的构建方式可以轻松添加新过程。本文包含有关SANC方法，数值验证和手册的理论描述。
In this paper we present a new Monte Carlo event generator ReneSANCe for simulation of processes at electron-positron colliders. In the current release of the generator the Bhabha scattering ($e^+e^- \to e^-e^+$) and Higgs-strahlung ($e^+e^- \to ZH$) process are implemented. Based on the SANC (Support for Analytic and Numeric Calculations for experiments at colliders) modules, the new generator takes into account complete one-loop and some higher-order electroweak radiative corrections with finite particle masses and polarizations. The new generator effectively operates in the collinear region and at the $ZH$ production threshold. It is constructed in such a way that new processes can be easily added. The paper contains a theoretical description of the SANC approach, numerical validations and manual.
