2 Oct 2003 | | Journal: | Phys.Rev. C68 (2003) 035204 | | Subject: | nucl-th | | Abstract: | With the global color symmetry model being extended to finite chemical potential, we study the density dependence of the local and nonlocal scalar quark condensates in nuclear matter. The calculated results indicate that the quark condensates increase smoothly with the increasing of nuclear matter density before the critical value (about 12$
ho_0$) is reached. It also manifests that the chiral symmetry is restored suddenly as the density of nuclear matter reaches its critical value. Meanwhile, the nonlocal quark condensate in nuclear matter changes nonmonotonously against the space-time distance among the quarks. | | Source: | arXiv, nucl-th/0310006 | | Services: | Forum | Review | PDF | Favorites | |
