论文摘要
我们根据自洽的SU（3）手性Quark-Soliton模型研究了Baryon解剖到Baryon Octet的电磁过渡形式因子，并考虑了风味SU（3）对称性的显式破坏的影响。我们强调电磁$ n \ toδ$过渡形式的$ q^2 $依赖性以及与实验和经验数据相比，$ e2/m1 $和$ e2/m1 $和$ c2/m1 $的比率。为了比较$ n \ toδ$的电磁过渡形式因子的当前结果与晶格QCD的结果，我们评估了与其物理价值偏离其物理价值的pion质量质量。 $ e2/m1 $和$ c2/m1 $比率的结果与晶格数据非常吻合。我们还介绍了解剖到八位位转换的电磁过渡形式因子的结果。
We investigate the electromagnetic transition form factors of the baryon decuplet to the baryon octet, based on the self-consistent SU(3) chiral quark-soliton model, taking into account the effects of explicit breaking of flavor SU(3) symmetry. We emphasize the $Q^2$ dependence of the electromagnetic $N\to Δ$ transition form factors and the ratios of $E2/M1$ and $C2/M1$ in comparison with the experimental and empirical data. In order to compare the present results of the electromagnetic transition form factors of the $N\to Δ$ with those from lattice QCD, we evaluate the form factors with the pion mass deviated from its physical value. The results of the $E2/M1$ and $C2/M1$ ratios are in good agreement with the lattice data. We also present the results of the electromagnetic transition form factors for the decuplet to the octet transitions.
