On the λ 'phi'4 - O(N) model at finite temperature
Description
The λΦ4-O(N) model is analyzed, in the leading 1/N approximation at finite temperature, with the conclusion that it is unstable above a certain temperature. The different scaling of the effective coupling of the effective coupling constant in p2 and T, and the behavior of the mass and of the bound state with T is also discussed. (author)

Analisa-se o modelo λΦ4-O(N) no limite da aproximacao 1/N a temperatura finita concluindo que e instavel acima de uma certa temperatura. Discutem-se escalas diferentes da constante de acoplamento efetiva em p2 e T, e o comportamento da massa e do estado ligado com T. (M.C.K.)Files
