Query: Chiral phase transition with mixing between scalar quarkonium and
  tetraquark   In the framework of 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 a sufficiently strong cubic self interaction of the tetraquark field can
drive the chiral phase transition to 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 vanishing density.
