摘要：

We calculate the two loop contributions within the ε-expansion to the Reggeon Field Theory scaling law for dσ/dt, derived using the renormalization group and a general renormalization point for the Pomeron propagator. This generalizes the O(ε) work of Abarbanel, Bartels, Bronzan, and Sidhu. The invariance of the results under certain coupling constant rescalings is demonstrated. We also make some qualitative comments regarding phenomenological applications. Our amplitude in a certain limit approximates the form of the low energy diffractive amplitude advocated by Kane. © 1979 Springer-Verlag.
