Title: "Chiral spin symmetry and stringy fluid"

Abstract: We discuss a new symmetry in QCD, the chiral spin symmetry, which is a symmetry of the confining electric interaction. Observation of this symmetry on the lattice at high temperatures, above the chiral symmetry restoration crossover, suggests a new regime/phase in QCD just between the hadron gas and the quark-gluon plasma, which is called a stringy fluid. We address the Nc¹ scaling of the thermodynamic quantities in the stringy fluid, which, along with symmetries, distinguishes this regime/phase from the hadron gas (N_c⁰) and from the QGP (N_c²). Finally we discuss a possible microscopic structure of the stringy fluid.
