Derivation of Bessel function closed-form solutions in zero dimensional φ(4)-field theory
The integral [Formula: see text] is used as an introductory learning tool in the study of Quantum Field Theory and path integrals. Typically, it is analyzed via perturbation theory. Closed-form solutions have been quoted for which I could not find any derivation. Using a simple and elegant transform...
