U(N) Gauge Model and Partial Breaking of N=2 Supersymmetry
Kazuhito Fujiwara, Hiroshi Itoyama, Makoto Sakaguchi
We briefly review a construction of N=2 supersymmetric U(N) gauge model in which rigid N=2 supersymmetry is spontaneously broken to N=1. This model generalizes the abelian model co…
Supersymmetric U(N) Gauge Model and Partial Breaking of N=2 Supersymmetry
Kazuhito Fujiwara, Hiroshi Itoyama, Makoto Sakaguchi
Guided by the gauging of U(N) isometry associated with the special Kahler geometry, and the discrete R symmetry, we construct the N=2 supersymmetric action of a U(N) invariant nona…
Whitham Prepotential and Superpotential
H. Itoyama, H. Kanno
N=2 supersymmetric U(N) Yang-Mills theory softly broken to N=1 by the superpotential of the adjoint scalar fields is discussed from the viewpoint of the Whitham deformation theory…
