Description:
Author(s): M. E. Carrington, B. A. Meggison, and D. Pickering It is well known that perturbative pressure calculations show poor convergence. Calculations using a two-particle irreducible (2PI) effective action show improved convergence at the 3 loop level, but no calculations have been done at 4 loops. We consider the 2PI effective theory for a symmetric scal… [Phys. Rev. D 94, 025018] Published Mon Jul 11, 2016
