NΔ（1232）跃迁形状因子比的低Q^2标度行为
Low-Q^2 scaling behavior of the form-factor ratios for the NΔ(1232)-transition
摘要：
讨论了核子电磁形状因子的标度行为。本文提出了一个具有自旋3/2重子共振的所有内部对称性、点不变性和规范不变性的NΔ（1232）电磁相互作用的一致拉格朗日量。点不变和规范不变的FF可以表现出准标度行为-虽然FF不达到渐近标度域，但其比值可以。在Q^2 > 0.4 GeV^2时，准标度假设与实验数据符合得很好。
英文摘要：
We address the issue of the scaling behavior of the nucleon electromagnetic form factors (FFs). We propose a consistent Lagrangian of the electromagnetic NΔ(1232)-interaction possessing all the internal symmetries of the spin-3/2 baryon resonance, point and gauge invariance. The point and gauge invariant FFs may exhibit quasi-scaling behavior--while the FFs do not reach asymptotic scaling domain, the ratios thereof do. The hypothesis of the quasi-scaling is in good agreement with the experimental data available at Q^2 > 0.4 GeV^2.
