Abstract The problem of finding which snalyticity properties of the production amplitudes are required to deduce, by mesns of the S-matrix unitarity relations, analyticity properties of scattering amplitudes as functions of the momentum transfer is solved. The fundamental feature of the results is that analyticity properties of the production amplitudes are required as functions of two and only two dynamical vsriables, whichever be the number of produced particles. The general method given does not require the actual calculation of any integral. In particular, for the production amplitudes a condition is given sufficient for the analyticity within an ellipse of the imaginary part of the scattering amplitude as function of the momentum transfer.
