摘要：

It is shown that the connection between even scattering lengths and σ terms of current algebra depends strongly upon dynamics. The σ terms for πΛ and π scattering are evaluated and shown to be consistent with a model algebra of current divergences in which the SU(3)-symmetry breaking parameter is not small. © 1969 The American Physical Society.
