    "abstract": "Using a confining, Dyson-Schwinger equation model of QCD at finite\ntemperature (T) and chemical potential (mu) we study the behaviour of \u003cq-bar\nq\u003e, m_pi, f_pi and the masses of the rho- and phi-mesons. For each of these\nquantities there is a necessary anticorrelation between its response to T and\nits response to mu. (-\u003cq-bar q\u003e) and f_pi decrease with T and increase with mu;\nm_pi is almost insensitive to T and mu until very near the border of the\nconfinement domain; and the mass of the longitudinal component of the vector\nmesons increases with T and decreases with mu. At T=0, the rho-meson mass is\nreduced by approximately 15% at nuclear matter density. These results are a\nconsequence of the necessary momentum-dependence of the dressed-quark\nself-energy.",
