PHASE-TRANSITIONS OF DENSE HADRONIC MATTER IN AN EXTENDED SKYRME MODEL ON S-3

We investigate the characteristics of phase transitions in dense hadro nic matter using the hypersphere approach in an extended Skyrme model which implements correctly the scale symmetry of QCD. The transition f rom a localized density phase to a delocalized uniform density phase i s found to be of first order at a critical radius of the hypersphere. Chiral restoration and gluon decondensation also take place at the sam e critical size of the hypersphere.
