摘要

我们利用统计框架和详细平衡原理研究了重子十倍子($J^P= \frac{3}{2}^+$)到八倍子($J^P= \frac{1}{2}^+$)的电磁四极转变。统计方法假定以各种夸克-胶子 Fock 态来展开强子。通过指定自旋、颜色 $\&$ flavorspace 中的适当倍率,计算出奇异和非奇异夸克-胶子 Fock 状态的相对概率。这些概率以统计参数的形式进一步积累,突出了海夸克和胶子在电磁转换中的重要性。我们的计算包括价和海(标量、矢量和张量)对重子过渡矩的各自贡献。通过加入奇异夸克质量,研究了味 SU(3) 对称性的影响及其在价夸克和海夸克中的破缺。海中的奇异性受到抑制因子$(1-C_l)^{n-1}$的约束,该因子取决于胶子的自由能。计算结果受影响高达60%,并显示出八重子海的主导地位。本研究与最新的实验数据和各种理论预测进行了比较,所得结果可为未来的实验研究提供重要启示。

Sea-quark dynamics in decuplet ($\frac{3}{2}^+$) $\rightarrow$ octet ($\frac{1}{2}^+$) transition quadrupole moment
We investigated the electromagnetic quadrupole transition of baryon decuplet ($J^P= \frac{3}{2}^+$) to octet ($J^P= \frac{1}{2}^+$) using the statistical framework together with the principle of detailed balance. The statistical approach assumed the expansion of hadrons in terms of various quark-gluon Fock states. By specifying the appropriate multiplicity in spin, color $\&$ flavor space, the relative probabilities of strange and non-strange quark-gluon Fock state are calculated. These probabilities further accumulated in the form of statistical parameters, highlighting the importance of sea quarks and gluons in the electromagnetic transition. Our calculations includes the individual contribution of valence and sea (scalar, vector and tensor ) to the transition moment of baryons. The effect of flavor SU(3) symmetry and its breaking in both valence and sea quarks is studied by incorporating the strange quark mass. The strangeness in the sea is constrained by a suppression factor $(1-C_l)^{n-1}$, which depends upon the free energy of gluons. The computed results get affected upto 60 $\%$ and exhibit the dominance of octet sea. The present work has been compared with updated experimental data and various theoretical predictions. The results obtained may offer important insights for future experimental studies.
