5 May 2000 | | Journal: | Phys.Lett. B484 (2000) 58-63 | | Subject: | hep-ph | | Affiliation: | Faculty of Physics, University of Bielefeld, Germany | | Abstract: | 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 $tapprox 10 fm$, we find a particle density of about $0.7/fm^3$ and a correlation length of $xi_{max}approx 2.5 fm$. The corresponding momentum spectra show a non-thermal behaviour. | | Source: | arXiv, hep-ph/0005051 | | Services: | Forum | Review | PDF | Favorites | |
