Wakeham efficiency reductions

现代高能物理实验数据的成功解释是一个复杂的过程。它不仅涉及数据点的实际测量，而且还涉及各种理论或现象学模型和过程的输入，这些模型和过程总是严重依赖于许多其他数据测量来进行调整和改进。新的理论思想带来了可以通过实验验证的预测，而新的实验发现则促使理论学家提出更好的想法。本提案的中心是HEPDATA项目，它有助于为这一过程提供数据输入。与此同时，位于达勒姆的粒子物理现象学研究所（IPPP）拥有广泛的现象学专业知识和强大的粒子理论基础，非常适合作为这个项目的东道主。HEPDATA项目的数据管理方面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。HEPDATA上的所有内容都是免费提供的，整个物理界都可以轻松访问，从而将数据推广到广泛的受众。此外，HEPDATA将继续与SLAC/SPIRES数据库项目保持联系，托管其英国镜像数据库，并与其替代数据库Inspire合作，长期提供镜像设施。英国伯克利粒子数据组的镜像网页也将继续由该项目托管。HEPDATA还将继续为Parton分布函数（PDF）代码提供服务器，并继续开发和维护PDF函数的LHAPDF库，这些函数将在包括LHC在内的大部分当前和未来的分析中使用。

The successful interpretation of data from modern high energy physics experiments is a complex process. It involves not only the actual measurement of data points but also the input of a variety of theoretical or phenomenological models and processes which invariably rely heavily on numerous other data measurements for their tuning and refinement. New theoretical ideas lead to predictions that can be tested experimentally, and new experimental findings challenge theorists to produce better ideas. The HEPDATA project at the centre of this proposal serves to facilitate the data input provision to this process. At the same time, the Institute of Particle Physics Phenomenology (IPPP) in Durham, with its wide-ranging expertise in phenomenology and a strong base in particle theory, is ideally suited to be the host of this project.The Data Curation aspect of the HEPDATA project will continue to compile HEP experimental scattering data and associated bibliographic information from particle physics experiments around the world. All the content on HEPDATA is freely available and easily accessible to the entire physics community, thereby promoting the data to a wide audience. In addition HEPDATA will continue its links with the SLAC/SPIRES database project, hosting its UK mirror and engaging with its replacement database Inspire, providing mirroring facilities in the long-term. The Berkeley Particle Data Group UK mirror web pages will also continue to be hosted by the project. HEPDATA will also continue to provide a server for Parton Distribution Function (PDF) codes and continue to develop and maintain the LHAPDF library of PDF functions which are used in a large part of present and future analyses including at the LHC.
