摘要In the framework of the two-flavor extended linear sigma model with mixing between scalar quarkonium and tetraquark, we investigate the role of the tetraquark in the chiral phase transition. We explore various scenarios depending on the value of various parameters in our model. The physical mass spectrum of mesons put a tight constraint on the parameter set of our model. We find that a sufficiently strong cubic self interaction of the tetraquark field can drive the chiral phase transition to the first order even at zero quark chemical potential. Weak or absence of the cubic self-interaction term of the tetraquark field make the chiral phase transition crossover at the vanishing density.
