Travel and Subsistence for the UKQCD Collaboration

此申请用于UKQCD合作三年的差旅和生活费，以资助合作会议，工作访问，研讨会和外部合作。这项合作由来自七所英国大学（剑桥、爱丁堡、格拉斯哥、利物浦、牛津、南安普顿和斯旺西）的60多名物理学家组成。在资助期间，我们将利用爱丁堡的QCDOC超级计算机，进行格点QCD模拟，包括质量接近其物理值的上、下和奇异夸克。主要研究项目包括：（a）量子色动力学参数（强耦合和夸克质量）;（B）强子结构（谱、混合和单重态介子、胶球、结构函数和分布振幅）;（c）弱矩阵元（B-和C-夸克现象学和K介子物理学）;（d）非零温度和有限重子密度下的量子色动力学相结构。进一步的工作涉及夸克动力学模拟算法，QCD计算机的设计和开发，以及通过国家（QCDgrid）和国际（International Lattice Data Grid）项目进行基于网格的数据存储和检索。

This application is for travel and subsistence for the UKQCD collaboration for three years to fund collaboration meetings, working visits, workshops and external collaboration. The collaboration comprises over 60 physicists from seven British universities (Cambridge, Edinburgh, Glasgow, Liverpool, Oxford, Southampton and Swansea). During the period of the grant we will be exploiting the QCDOC supercomputer in Edinburgh, performing lattice QCD simulations with the inclusion of up, down and strange quarks with masses close to their physical values. Principal research projects include: (a) QCD parameters (strong coupling and quark masses) ; (b) Hadron structure (spectrum, hybrid and singlet mesons, glueballs, structure functions and distribution amplitudes); (c) Weak matrix elements (b- and c-quark phenomenology and kaon physics); (d) QCD phase structure at non-zero temperature and finite baryon density. Further work addresses algorithms for dynamical quark simulations, design and development of QCD computers, and grid-based data storage and retrieval via national (QCDgrid) and international (International Lattice Data Grid) projects.
