Properties of JP = 1/2+ baryon octets at low energy

Amanpreet Kaur, Pallavi Gupta, Alka Upadhyay

摘要:

该统计模型结合细致平衡原理,能够唯象地计算和分析与自旋和味相关的性质,如磁矩(有有效质量、有效电荷、有有效质量和有效电荷)、夸克自旋极化和分布、奇异抑制因子等。在统计模型下分析了八重态重子的磁矩,着重讨论了奇异夸克与非奇异夸克质量差引起的SU(3)对称性破缺效应.本文的工作假设强子与一个含有夸克-胶子Fock态混合物的海。所得结果与理论模型和实验数据进行了比较。

英文摘要:

The statistical model in combination with detailed balance principle is able to phenomenological calculate and analyze spin and flavor dependent properties like magnetic moments (with effective masses, effective charge, with both effective mass and effective charge), quark spin polarization and distribution, strangeness suppression factor. The magnetic moments of the octet baryons are analyzed within the statistical model, by putting emphasis on the SU(3) symmetry breaking effects generated by the mass difference between the strange and non strange quarks. The work presented here assume hadrons with a sea having admixture of quark-gluon Fock states. The results obtained have been compared with theoretical models and experimental data.
