The Pressure of Hot $g^2{\varphi }^4$ Theory at order $g^5$

Abstract

The order $g^5$ contribution to the pressure of massless $g^2{\varphi }^4$ theory at nonzero temperature is obtained explicitly. Lower order contributions are reconsidered and two issues leading to the optimal choice of rearranged Lagrangian for such calculations are clarified.
