论文摘要
光谱的光谱奇怪的重子是一个重要方面，其共鸣仍然未知。本文档的重点是$δ$ baryons，与早期的工作不同，在这里，所有四个Isospin State均已分别获得了具有不同组成质量的U和D Quarks。计算共振质量的理论框架是高中性夸克模型（HCQM）。限制电势与线性形式一样，以及添加自旋依赖性和一阶校正项。将获得的结果与许多不同的方法以及实验可用的状态进行了比较。除了质谱外，还绘制了（n，$ m^{2} $）和（j，$ m^{2} $）的regge轨迹。磁矩和过渡磁矩已经使用有效的夸克质量计算出来。辐射衰减宽度已以$δ^{+} $和$δ^{0} $ Channels进行了研究。
The spectroscopy of light, strange baryons have been an important aspect with still unknown resonances and intrinsic baryonic properties. The present document is focused on the $Δ$ baryons unlike earlier work, here all the four isospin states have been separately obtained treating u and d quarks with different constituent masses. The theoretical framework for calculating the resonance masses is hypercentral Constituent Quark Model (hCQM). The confining potential is taken as of linear form alongwith the addition of spin-dependent as well as first order correction term. The results obtained have been compared with many varied approaches as well as experimental available states. In addition to mass spectra, Regge trajectories for (n,$M^{2}$) and (J,$M^{2}$) have been plotted. The magnetic moment as well as transition magnetic moment have been calculated using effective quark mass. The radiative decay width has been studied for $Δ^{+}$ and $Δ^{0}$ channels.
