MULTIPERIPHERAL DYNAMICS AT ZERO MOMENTUM TRANSFER

Following a suggestion by Goldberger and Low, the crude multi-Regge bootstrap model of Chew and Pignotti is reformulated through a generalization of the physical-region integral equation discovered in 1962 by Fubini and collaborators. When consideration is restricted to zero momentum transfer, Lorentz symmetry permits almost complete diagonalization of the kernel, Lorentz poles corresponding to eigenvalues thereof. Cuts also appear but in a manner dynamically and unambiguously related to the poles. Being an expression of unitarity, the equation encompasses absorptive" effects. © 1969 The American Physical Society."
