核子手征对称性的标量响应与核物质性质

Scalar response of the nucleon chiral symmetry and nuclear matter properties

G. Chanfray, M. Ericson

摘要:

在这次演讲中,我们提出了一个描述的手征方法的基础上存在的手征不变标量场与通过自发的手征对称性破缺的质量的产生核结合。我们讨论了这样一个领域的NJL模型的例子。我们还将约束的影响,在核子子结构的水平,以稳定的核物质。在一个特殊的夸克-双夸克模型中,我们讨论了自发手征对称性破缺和禁闭对核子质量和核物质描述的同时影响。

英文摘要:

In this talk we present a description of nuclear binding in a chiral approach based on the existence of a chiral invariant scalar field associated with the generation of the masses through spontaneous chiral symmetry breaking. We discuss the emergence of such a field on the example of the NJL model. We also incorporate the effect of confinement at the level of the nucleon substructure to stabilize nuclear matter. In a particular quark-diquark model we illustrate the simutaneous influences of spontaneous chiral symmetry breaking and confinement on the nucleon mass and on the nuclear matter description.
