Abstract
We consider the O(N)-symmetric phi(4) theory in two and three dimensions and determine the nonperturbative mass renormalization needed to obtain the phi(4) continuum theory. The required nonperturbative information is obtained by resumming high-order perturbative series in the massive renormalization scheme, taking into account their Borel summability and the known large-order behavior of the coefficients. The results are in good agreement with those obtained in lattice calculations.| File | Dimensione | Formato | |
