最近的实验表明，有效赝标量项的符号与Goldberger和Treiman基于V-A理论和色散关系技术的理论结果不同。对这种差异提出了可能的解释。结果表明，哈密顿量中一个很小的伪标量项(相当于有效伪标量项的1/100)可以改变有效伪标量项的符号。如果将这一小项变换并作为普遍的轴向矢量电流的一部分添加，它在β衰变和pi-Mu+Nu衰变中几乎不会产生任何影响。超子对的包含也被考虑在内。(身份验证)
Recent experiments indicate that the sign of the effective pseudoscalar term in mu -capture reactions is different from the theoretical result of Goldberger and Treiman, based on V-A theory and dispersion relation technique. A possible explanation of this difference is proposed. It is shown that a very small pseudoscalar term in the Hamiltonian (of the order 1/100 of the effective pseudoscalar term) can change the sign of the effective pseudoscalar term. If this small term is transformed and added as a part of the universal axial vector current, it produces practically no effect in beta and pi - mu + nu decay. The inclusion of hyperon pairs was also considered. (auth)
