标题： Axial-vector form factors of the baryon octet and chiral symmetry

摘要： 我们考虑重子八重态在味-SU(3)手征微扰理论中的轴矢量形式因子。 重子八重态和十重态以及赝标介子八重态被作为显式自由度包含进来。 我们探讨在轴矢量形式因子的一圈贡献中使用实壳介子和重子质量，并着重于在手征幂次计数方面的一致处理。 对这种方法的收敛性质进行了仔细研究。 我们讨论与即将到来的QCD格点数据比较的潜力。 显示英文摘要

摘要： We consider the axial-vector form factors of the baryon octet in flavor-SU(3) chiral perturbation theory. The baryon octet and decuplet and the pseudoscalar-meson octet are included as explicit degrees of freedom. We explore the use of on-shell meson and baryon masses in the one-loop contributions to the axial-vector form factors and focus on a consistent treatment in terms of chiral power counting. The convergence properties of such an approach are scrutinized. We discuss the potential for comparison to upcoming QCD lattice data.
