Practical analyticity of scattering amplitudes
Yu. S. Vernov, M. S. Chubarov
Abstract:
It is shown that for arbitrary scattering process of two particles and for arbitrary values of momentum transfer, the function can be constructed which is analytical in the largest possible domain and at the same time approximates the scattering amplitude for all physical energy values with arbitrarily high precision.
