Light Hadronen Phänomenologie

DESY小组是QCDSF合作的核心，将产生具有动态夸克的规范场构型。其目的是产生分布在广泛裸参数范围内的构型，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单位内的其他小组作进一步分析。DESY小组的物理项目将集中在轻强子现象学上。研究的主题包括光强子谱、夸克质量、运行耦合常数as、核子形状因子、核子的深度非弹性结构函数（包括高扭、弱矩阵元素和衰变常数的贡献）、QCD真空动力学和夸克约束机制。此外，我们将把我们关于微扰和非微扰重整化和改进的工作扩展到动态夸克的情况。

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.
