The DESY group forms the core of the QCDSF collaboration and will generate the gauge field configurations with dynamical quarks. The aim is to produce configurations spread over a wide range of bare parameters so that an extrapolation of the physical results to the continuum and chiral limit can be performed. These configurations will be made available to other teams within the research unit for further analysis. The physic´s program of the DESY group will focus on light hadron phenomenology. The topics to be studied are the light hadron spectrum, quark masses, the running coupling constant as, nucleon form factors, the deep-inelastic structure functions of the nucleon including contributions of higher-twist, weak matrix elements and decay constants, and the dynamics of the QCD vacuum and the quark confinement mechanism. Furthermore, we will extend our work on perturbative and non-perturbative renormalization and improvement to the case of dynamical quarks.

DESY群构成了QCDSF合作的核心，并将产生具有动力学夸克的规范场组态。其目的是产生分布在广泛的裸参数范围内的组态，以便可以将物理结果外推到连续统和手性极限。这些配置将提供给研究股内的其他小组作进一步分析。DESY小组的物理S计划将专注于轻强子现象学。要研究的问题包括轻强子能谱、夸克质量、运行耦合常数As、核子形状因子、核子深非弹性结构函数，包括高扭度、弱矩阵元和衰变常数的贡献，以及QCD真空和夸克禁闭机制的动力学。此外，我们将把我们在微扰和非微扰重整化和改进方面的工作推广到动力学夸克的情况。
