超中心夸克模型中轻味重子的性质

Properties of Light Flavour Baryons in Hypercentral quark model

Kaushal Thakkar, Bhavin Patel, Ajay Majethiya, P. C. Vinodkumar

摘要:

在夸克模型中,利用三体系统的超中心描述研究了轻味重子。约束势被假定为超中心库仑加功率势($hCPP_ν$),功率指数为$ν$。计算了轻味重子在不同幂指数$ν$(从0.5到1.5)下的质量和磁矩。预测的质量和磁矩被发现达到一个饱和值,相对于在$ν$的变化超过功率指数$ν>$ 1.0。进一步计算了轻味重子的跃迁磁矩和辐射衰变宽度。结果与已知的实验以及其他理论模型吻合良好。

英文摘要:

The light flavour baryons are studied within the quark model using the hyper central description of the three-body system. The confinement potential is assumed as hypercentral coulomb plus power potential ($hCPP_ν$) with power index $ν$. The masses and magnetic moments of light flavour baryons are computed for different power index, $ν$ starting from 0.5 to 1.5. The predicted masses and magnetic moments are found to attain a saturated value with respect to variation in $ν$ beyond the power index $ν>$ 1.0. Further we computed transition magnetic moments and radiative decay width of light flavour baryons. The results are in good agreement with known experimental as well as other theoretical models.
