Abstract

We construct on-shell N=2 nonlinear sigma models on SO(2N)/U(N) and Sp(N)/U(N) by holomorphically embedding the models in the hyper-Kähler nonlinear sigma model on the cotangent bundle of the Grassmann manifold T^∗ G_2N,N in the N=1 superspace formalism. We apply the moduli matrix formalism to the mass-deformed nonlinear sigma models on the quadrics to study three-pronged junctions by using a recently proposed diagram method.
