The chiral phase transition at a certain critical temperature is a restoration mechanism of the chiral symmetry, broken by the nonzero mass of quarks and mesons. The transition can be studied through several models, among which are the σ models. An analysis is made on the linear and nonlinear σ models with different approximations, and we show that the transition is of second order in both cases.

La transición en la fase quiral a una cierta temperatura crítica es una restauración del mecanismo de la simetría quiral, rota debido a la masa finita de los quarks y los mesones. La transición puede ser estudiada a través de varios modelos, entre los cuales estan los modelos σ. Se hace un análisis sobre la base de los modelos σ lineales y no lineales con diferentes aproximaciones, y se muestra que la transición es de segundo orden en ambos casos.
