Multiscalar amplitudes to all orders in perturbation theory
A method for calculating loop amplitudes at the multiboson threshold is presented, based on Feynman-diagram techniques. We explicitly calculate the one-loop amplitudes in both $\phi^4$-symmetric and broken symmetry cases, using dimensional regularization. We argue that, to all orders in the perturba...
