8 Nov 2001 | | Journal: | Phys.Rev. D65 (2002) 091504 | | Subject: | Nuclear Theory; Superconductivity | nucl-th cond-mat.supr-con hep-ph nucl-ex | | Abstract: | We investigate possible precursory phenomena of color superconductivity in quark matter at finite temperature T with use of a simple Nambu-Jona-Lasinio model. It is found that the fluctuating pair field exists with a prominent strength even well above the critical temperature T_c. We show that the collective pair field has a complex energy located in the second Riemann sheet, which approaches the origin as T is lowered to T_c. We discuss the possible relevance of the precursor to the observables to be detected in heavy ion collisions. | | Source: | arXiv, nucl-th/0111022 | | Services: | Forum | Review | PDF | Favorites | |
