Renormalizable means singular
Presented by Kevin Cahill (UNM)
Some nonrenormalizable theories are less singular than all renormalizable theories. One can use lattice simulations to extract physical information from these nonsingular nonrenormalizable theories. This paper discusses four nonrenormalizable theories that have finite euclidian and minkowskian Green's functions. Two of them have finite energy densities and describe scalar bosons of finite mass. The space of nonsingular nonrenormalizable theories is vast.
