6 Dec 2002 | | Journal: | Nucl.Phys. A721 (2003) 285-288 | | Subject: | hep-ph nucl-th | | Abstract: | We investigate possible precursory phenomena of color superconductivity at finite temperature $T$ with an effective theory of QCD. It is found that the fluctuation of the diquark pair field exists with a prominent strength even well above the critical temperature $T_c$. We show that such a fluctuaiton forms a collective mode, the corresponding pole of which approaches the origin as $T$ is lowered to $T_c$ in the complex energy plane. We discuss the possible relevance of the precursor to the observables to be detected in heavy-ion collisions. | | Source: | arXiv, hep-ph/0212096 | | Services: | Forum | Review | PDF | Favorites | |
