Scattering and reflection positivity in relativistic Euclidean quantum mechanics
Scattering and reflection positivity in relativistic Euclidean quantum mechanics
In this paper I exhibit a class of reflection-positive Euclidean invariant four-point functions that can be used to formulate a Poincar\'e invariant quantum theory. I demonstrate the existence of scattering wave operators, which can be calculated without analytic continuation in this representation.
