Strong-Coupling ${\varphi }^4$-Theory in $4-\epsilon$ Dimensions and Critical Exponents

Abstract

With the help of variational perturbation theory we continue the renormalization constants ${\varphi }^4$-theories in $4-\epsilon$ dimensions to strong bare couplings $g_0$ and find their power behavior in $g_0$, thereby determining all critical exponents without renormalization group techniques.
