Triviality in a Non-Perturbative Second-Order Mean-Field Theory for $\phi^4_4$
For a second-order mean-field truncation of the four-dimensional phi^4 Wilson-Polchinski hierarchy, solutions exist for any positive bare coupling, and both the constant and quadratic momentum sectors vanish in the ultraviolet limit.
