TMDlib和TMDEXP:横向动量相关部分子分布的库和绘图工具
TMDlib and TMDplotter: library and plotting tools for transverse-momentum-dependent parton distributions
摘要:
横动量相关分布(TMD)是高能物理中理论和唯象两方面的核心问题。在本手册中,我们介绍了库,TMDlib,横向动量相关的部分子分布函数(TMD PDF)和碎裂函数(TMD FF)的拟合和参数化,以及在线绘图工具,TMDlib。我们提供了一个程序组件和不同的物理框架,用户可以通过可用的参数化访问的描述。
英文摘要:
Transverse-momentum-dependent distributions (TMDs) are central in high-energy physics from both theoretical and phenomenological points of view. In this manual we introduce the library, TMDlib, of fits and parameterisations for transverse-momentum-dependent parton distribution functions (TMD PDFs) and fragmentation functions (TMD FFs) together with an online plotting tool, TMDplotter. We provide a description of the program components and of the different physical frameworks the user can access via the available parameterisations.
