A data curation and simulation facility for particle physics

现代高能粒子物理实验数据的成功解释是一个复杂的过程，不仅涉及数据点本身的实际测量，而且涉及各种理论或现象学模型和过程的输入。位于达勒姆的粒子物理现象学研究所（IPPP）拥有强大的现象学基础，非常适合满足这一需求，本拨款申请中提出的项目将以两种相关方式实现这一目标：(1)数据管理。HEPDATA项目将继续编纂来自世界各地粒子物理实验的HEP实验散射数据和相关书目信息，并将这些数据免费提供给整个物理学界，从而使数据易于获取，并将数据推广给广泛的受众。它还将继续托管SLAC/SPIRES数据库的英国镜像和伯克利PDG网页，这些网页被HEP研究计划大量使用。HEPDATA还将继续为Parton分布函数（PDF）代码提供服务器，并开发和维护LHAPDF（新的PDF函数库），用于未来的分析，包括LHC。(2)数据仿真。Herwig++是大型强子对撞机分析中使用的关键事件生成器之一。Herwig++的大部分全球专业知识现在都在达勒姆。我们将继续开发Herwig++，并提供长期所需的基本支持和开发，使Herwig++成为实验项目的核心分析工具。

The successful interpretation of data from modern high energy particle physics experiments is a complex process involving not only the actual measurement of data points themselves but also the input of a variety of theoretical or phenomenological models and processes. The Institute for Particle Physics Phenomenology (IPPP) in Durham, with its strong phenomenological base is ideally suited to address this need and the projects proposed in this grant application serve to do this in two related ways: (1) Data Curation. The HEPDATA project will continue to compile HEP Experimental scattering data and associated bibliographic information from particle physics experiments around the world and make these freely available to the entire physics community, thereby making data easily accessible and promoting the data to a wide audience. It will also continue to host the UK mirror of the SLAC/SPIRES databases and the Berkeley PDG web pages which are heavily used by the HEP research program. HEPDATA will also continue to provide a server for Parton Distribution Function (PDF) codes and develop and maintain LHAPDF the new library of PDF funtions for use in future analyses, including the LHC. (2) Data Simulation. Herwig++ is one of the key event generators which will be used in the LHC analyses. A large fraction of the worldwide expertise in Herwig++ is now based at Durham. We will continue to develop Herwig++ and provide the essential support and development needed in the longer term to make Herwig++ a core analysis tool for the experimental progamme.
