Theoretical advances in parton showers (B1d)

蒙特卡罗事件发生器对粒子物理学的重要性，特别是对大型哈登对撞机研究计划的重要性，怎么强调都不过分。部分子簇射是每个发生器的关键部分。在这个计画中，我们打算设计一个包含干涉效应、高阶分裂和软函数的对数精度更高的部分子簇射。概念性的工作将最终实现在框架内的著名发电机Herwig。

The importance of Monte Carlo event generators for particle physics in general and the Large Hardon Collider research programme in particular cannot be overstated. The parton shower is a crucial part of every generator. In this project, we intend to devise a parton shower with higher logarithmic accuracy by including interference effects and higher order splitting and soft functions. The conceptual work will culminate in an implementation in the framework of the well known generator Herwig.
