    Full text link
    The determination of the parameters of the deconfining transition in N_f=2 QCD is discussed, and its relevance to the understanding of the mechanism of color confinement.Comment: 10 pages. In honour of Yu. A. Simonov on his seventyth birthday; to be published in Yadernaya Fizik

    Relativistic mass distribution in event-anti-event system and ``realistic'' equation of state for hot hadronic matter

    We find the equation of state p,ρT6,p,\rho \propto T^6, which gives the value of the sound velocity c2=0.20,c^2=0.20, in agreement with the ``realistic'' equation of state for hot hadronic matter suggested by Shuryak, in the framework of a covariant relativistic statistical mechanics of an event--anti-event system with small chemical and mass potentials. The relativistic mass distribution for such a system is obtained and shown to be a good candidate for fitting hadronic resonances, in agreement with the phenomenological models of Hagedorn, Shuryak, {\it et al.} This distribution provides a correction to the value of specific heat 3/2, of the order of 5.5\%, at low temperatures.Comment: 19 pages, report TAUP-2161-9

    Chromomagnetic Catalysis of Color Superconductivity in a (2+1)-dimensional NJL Model

    Get PDF
    The influence of a constant uniform external chromomagnetic field HH on the formation of color superconductivity has been investigated. The consideration was performed in the framework of a (2+1)-dimensional Nambu--Jona-Lasinio model with two different four-fermionic structures responsible for anddiquark and diquark condensates. In particular, it was shown that there exists a critical value HcH_c of the external chromomagnetic field such that at H>HcH>H_c a nonvanishing diquark condensate is dynamically created (the so-called chromomagnetic catalysis effect of color superconductivity). Moreover, external chromomagnetic fields may in some cases enhance the diquark condensate of color superconductivity.Comment: 32 pages, 2 figures, revte
