从Mandelsthm表象出发，导出了π-核子散射的分波色散关系。该表示的对称性被用来获得非物理分支切割上的不连续性的表达式。这些表达式包括了π-核子散射的散射幅度和pi+pi产生N+N的过程。在忽略除最近奇点之外的所有奇点的近似下，证明了Chew-low有效射程公式是该方程的解。(身份验证)
Partial-wave dispersion relations for pion-nucleon scattering were derived from the Mandelsthm representation. The symmetry of the representation was used to obtain expressions for the discontinuities across the unphysical branch cuts. These expressions involved scattering amplitudes for pion-nucleon scattering and for the process pi + pi yields N + N. In the approximation of neglecting all but the nearest singularities, it was shown that the Chew-Low effective-range formula is a solution to the equations. (auth)
