Description

We study the implications of a light tetraquark on the chiral phase transition at nonzero temperature T: the behavior of the chiral and fourquark condensates and the meson masses are studied in the scenario in which the resonance f0(600) is described as a predominantly tetraquark state. It is shown that the critical temperature is lowered and the transition softened. Interesting mixing effects between tetraquark and quarkonium configurations take place. (author)
