| dc.description | Suppose a regularised functional integral depends holomorphically on a parameter that receives only a finite renormalization. Can one expect the correlation functions to retain the analyticity in the parameter after removal of the cutoff(s)? We examine the issue in the Sinh-Gordon theory by computing the intrinsic 4-point coupling as a function of the Lagrangian coupling β. Drawing on the conjectured triviality of the model in its functional integral formulation for β^2 > 8π, and the weak-strong coupling duality in the bootstrap formulation on the other hand, we conclude that the operations: ``Removal of the cutoff(s)'' and ``analytic continuation in β'' do not commute. | |
