K1/K⁎ enhancement as a signature of chiral symmetry restoration in heavy ion collisions
Based on the fact that the mass difference between the chiral partners is an order parameter of chiral phase transition and that the chiral order parameter reduces substantially at the chemical freeze-out point in ultra-relativistic heavy ion collisions, we argue that the production ratio of K1 over...
