首次LHC p-Pb运行后的核PDF状态

Status of nuclear PDFs after the first LHC p-Pb run

Hannu Paukkunen

摘要:

本文综述了核部分子分布函数的全局分析的最新进展。首先介绍了当代适合后,分析程序迅速召回和模糊的实验数据的使用概述。各种核PDF参数化进行了比较和解释的主要差异。讨论了核PDF在LHC p-Pb硬过程观测量中的作用,并展望了未来的发展前景。

英文摘要:

In this talk, I overview the recent progress on the global analysis of nuclear parton distribution functions (nuclear PDFs). After first introducing the contemporary fits, the analysis procedures are quickly recalled and the ambiguities in the use of experimental data outlined. Various nuclear-PDF parametrizations are compared and the main differences explained. The effects of nuclear PDFs in the LHC p-Pb hard-process observables are discussed and some future prospects sketched.
