摘要：

We investigate the decay of metastable states with broken CP-symmetry which have recently been proposed by Kharzeev, Pisarski and Tytgat to form in hot hadronic matter. We consider the efficiency of the amplification of the eta'-field via parametric resonance, taking the backreaction into account. For times of the order t approximate to 10 fm, we find a particle density of about 0.7/fm(3) and a correlation length of xi(max) approximate to 2.4 fm. The corresponding momentum spectra show a non-thermal behaviour. (C) 2000 Elsevier Science B.V. All rights reserved.
