光锥上的奇异和非奇异重子性质

Exotic and Non-Exotic Baryon Properties on the Light Cone

Cédric Lorcé

摘要:

本文基于光锥波函数的手征夸克孤子模型,研究了轻奇异重子和非奇异重子的静态性质。我们特别讨论了矢量,轴向和张量电荷以及重子八重态,十重态和假设的反十重态的电磁矩的估计。贡献福克组件的七夸克部门被认为是相当大的,反映了π介子云的重要性。所有这些观测量进一步分解为味夸克、价夸克、海夸克和反夸克的贡献。

英文摘要:

We present an extensive study of the static properties of light exotic and non-exotic baryons, based on the formulation of chiral quark-soliton model in terms of light-cone wave functions. We discuss in particular vector, axial and tensor charges as well as an estimation of the electromagnetic moments for the baryon octet, decuplet and hypothetical antidecuplet. Contributions from Fock components up to the seven-quark sector are considered and appear to be sizeable, reflecting the importance of the pion cloud. All these observables are further decomposed into flavor, valence quark, sea quark and antiquark contributions.
