## Abstract

Using both the matrix model prescription and the strong-coupling approach, we describe the intersections of n = 0 and n = 1 non-degenerated branches for quartic (polynomial of adjoint matter) tree-level superpotential in M = 1 supersymmetric SO(N)/USp(2N) gauge theories with massless flavors. We also apply the method to the degenerated branch. The general matrix model curve on the two cases we obtain is valid for arbitrary N and extends the previous work from strong-coupling approach. For SO (N) gauge theory with equal massive flavors, we also obtain the matrix model curve on the degenerated branch for arbitrary N. Finally we discuss on the intersections of n = 0 and n = 1 non-degenerated branches for equal massive flavors.
