Descripción: The thermodynamics of the massive <math>\lambda\varphi^{4}+\sigma\varphi^{6}\,\!</math> model is analysed at finite temperature in the two-loop approximation. The behavior of the thermal mass and coupling constant is discussed. We demonstrate in the two-loops approximation the existence of a tricritical point.
