摘要：

The possibility of the existence of an infinite family of Lorentz poles is investigated using a dynamical model. For spinless scalar particles (mass m) scattering via the exchange of another spinless scalar particle (mass μ), the Bethe-Salpeter equation is solved in two limiting cases, μ=0 and μ→. In both cases it is shown that the O(4) projected amplitude is meromorphic in n (the four-dimensional angular momentum) and that there are an infinite number of poles in the n plane. © 1968 The American Physical Society.
