CrossingSymmetric Bootstrap and Exponentially Falling Form Factors
Abstract
It is shown that form factors with the asymptotic behavior F(t)~exp(t^{12}) are a consequence of the nonlinear boundstate equation for the wave function in the crossingsymmetric bootstrap model. This nonlinear equation incorporates the notion that the constituent particles are themselves composite. The result is obtained both from the Schrödinger equation and the BetheSalpeter equation; in the latter case, it is argued that the result should be valid for a wide class of interaction kernels.
