Infrared finitness and analyticity properties of the loop–loop scattering amplitudes in gauge theories
Differently from the parton–parton scattering amplitudes, which are known to be affected by infrared (IR) divergences, the elastic scattering amplitude of two colourless states in gauge theories, e.g., two qq̄ meson states, is expected to be an IR–finite physical quantity. It was shown in Refs. [1,2,3] that the high–energy meson–meson elastic scattering amplitude can be approximately reconstruct...
متن کاملAnalyticity Properties of the Anisotropic Heisenberg Model
An upper bound Te for the critical temperature of a class of spin systems which includes the Heisenberg ferromagnet is derived. The analyticity of the free energy as a function of the temperature, the external magnetic field, and the interaction potentials, is demonstrated in a domain which includes all temperatures T > Tc For the isotropic Heisenberg ferromagnet in v dimensions we find the poo...
متن کاملMultiscalar Production Amplitudes beyond Threshold
We present exact tree-order amplitudes for H → n H , for final states containing one or two particles with non-zero three-momentum, for various interaction potentials. We show that there are potentials leading to tree amplitudes that satisfy unitarity, not only at threshold but also in the above kinematical configurations and probably beyond. As a by-product, we also calculate 2 → n tree amplit...
متن کاملResults on the Analyticity of Many - Body Scattering Amplitudes in Perturbation Theory
The problem of analytic continuation of the many-body scattering amplitude associated with a perturbation-theory diagram under the rotation of the final momenta from real to complex momenta, k -.. (1 + iO)k, is studied. It is shown that the contour of integration over internal momenta can be distorted avoiding singularities of the integrand, as 0 varies for small enough O. If the diagram is con...
متن کاملAnalyticity and Crossing Symmetry of the Eikonal Amplitudes in Gauge Theories
After a brief review and a more refined analysis of some relevant analyticity properties (when going from Minkowskian to Euclidean theory) of the high–energy parton–parton and hadron–hadron scattering amplitudes in gauge theories, described nonperturbatively, in the eikonal approximation, by certain correlation functions of two Wilson lines or two Wilson loops near the light cone, we shall see ...
