Abstract
We study the implications of a light tetraquark on the chiral phase transition at nonzero temperature : The behavior of the chiral and four-quark condensates and the meson masses are studied in the scenario in which the resonance 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.
