The scalar-type nonlinear term hastens the chiral phase transition,the scalar-vector mixing term suppresses effects of the vector-type linear term and the scalar-diquark mixing term makes the coexisting phase wider.5 pages, 2 figures, to be published in the proceedings for the YONUPA Summer School 2006, Nagano, August 5-10, 2006Nuclear TheoryHigh Energy Physics - Phenomenologytext
