层子模型中重子的半轻子衰变和高能中微子反应

本文从层子模型的结构观点出发,应用文献1]中的层子与轻子的弱相互作用等效哈密顿量和文献2]中给出的(1/2)⁺重子波函数及文献3]中定出的参数,对(1/2)⁺重子的半轻子衰变和高能中微子的弹性和准弹性反应进行了讨论。文中得到的(1/2)⁺重子的半轻子衰变的理论结果与实验符合较好;得到的ΔS=0过程的轴矢形状因子和ν_μ+n→p+μ^-过程的截面在误差范围内均与实验相符合;得到的ΔS=1过程的轴矢形状因子和ν_μ+p→Λ+μ⁺过程的截面与目前实验给出的粗略结果也是符合的。特别需要指出的是,本文在讨论反应问题时,理论中所包含的参数全部从电磁过程定出,在给出的轴矢形状因子和截面公式中没有引进新的参数。

SEMI-LEPTONIC DECAYS OF THE BARYONS AND HIGH-ENERGY NEUTRINO REACTIONS IN THE STRATON MODEL

On the basis of the structural model of stratons, we discuss semi-leptonic decays of (1/2)⁺ baryons and elastic and quasi-elastic neutrino reactions, using the effective Ha-miltonian of weak interaction for stratons and leptons in 1] and the (1/2)⁺ baryon wave functions in 2] and the parameters determined by electromagnetic processes in 3]. The theoretical results of the semi-leptonic decays are in good agreement with the experimental results. The axial-vector form factor of △S = 0 processes and the total cross-sections of ν_μ+n→p+μ^- agree with experiments within reasonable error. The axial-vector form factor of △S = 1 processes and the total cross-sections of ν_μ+p→Λ+μ⁺ also agree with the rough experimental data available.In particular, it is of interest to point out that, in our discussion, all the parame-ters involved were determined in 3], no new parameter has been introduced.
