论文摘要
我们研究了手性夸克 - 索尔顿模型框架内巴属八位骨的轴向矢量过渡形式因子，其中包括风味su（3）对称性破裂的影响。我们将旋转$ 1/n_c $校正考虑，并将奇怪的当前夸克质量视为扰动。我们将$δ\的当前结果与其他模型和晶格QCD的结果进行比较。我们还计算了从重骨解剖到八位位的所有可能的轴向矢量过渡，奇怪的变化，即$ |ΔS| = 1 $。我们在零动量传输（$ q^2 = 0 $）下获得$δ\ to n $ axial-vector转换的基本形式$ c_5^a $的值。此外，目前的结果与与T2K数据的人非常吻合。与数据相比，我们提取轴向矢量质量$ m_a $的值。
We investigate the axial-vector transition form factors of the baryon octet to the baryon decuplet within the framework of the chiral quark-soliton model, with the effects of flavor SU(3) symmetry breaking included. We consider the rotational $1/N_c$ corrections and regard the strange current quark mass as a perturbation. We compare the present results for the $Δ\to N$ axial-vector transition with those from other models and lattice QCD. We also compute all possible axial-vector transitions from the baryon decuplet to the octet with the strangeness changed, i.e., $|ΔS|=1$. We obtain the value of the essential form factor $C_5^A$ for the $Δ\to N$ axial-vector transition at the zero momentum transfer ($Q^2=0$). Furthermore, the present results are in good agreement with those fitted with the T2K data. We extract the value of the axial-vector mass $M_A$ compared to the data.
