强子Bethe-Salpeter模型中广义部分子分布的支集

Support of generalized parton distributions in Bethe-Salpeter models of hadrons

A. Van Dyck, T. Van Cauteren, J. Ryckebusch

摘要:

研究了具有点状组分的相对论组分夸克模型中广义部分子分布的本征支集。当顶点函数不依赖于相对负动量时,保证了正确的支集。我们表明,包括夸克相互作用的模型与点状组分夸克可能会导致一个支持问题。本文计算了波恩相对论组分夸克模型中支撑问题的大小。

英文摘要:

The proper support of generalized parton distributions from relativistic constituent quark models with pointlike constituents is studied. The correct support is guaranteed when the vertex function does not depend on the relative minus-momentum. We show that including quark interactions in models with pointlike constituent quarks might lead to a support problem. A computation of the magnitude of the support problem in the Bonn relativistic constituent quark model is presented.
