| dc.description | In this paper we use Modified Self-Consistent Resummation (MSCR) in order to obtain the scalar dressed mass by evaluating the self-energy up to two loops in the neutral scalar $λϕ^4$ model at finite temperature. With this laboratory model we show that, if a theory is renormalizable at zero temperature, using the MSCR it is always possible to obtain a finite corrected mass at finite temperature. This feature of the MSCR is not observed in some other approximation techniques usually found in the literature. | |
