Contribution
It provides a detailed analysis of spontaneous partial breaking of N=2 supersymmetry to N=1 in U(N) gauge models, including mass spectra and relations to matrix models.
Findings
N=2 supersymmetry is spontaneously broken to N=1 on vacua
Gauge symmetry breaks to a product gauge group
Masses of supermultiplets are explicitly given
Abstract
We briefly review the properties of the N=2 U(N) gauge model with/without matters. On the vacua, N=2 supersymmetry and the gauge symmetry are spontaneously broken to N=1 and a product gauge group, respectively. The masses of the supermultiplets appearing on the N=1 vacua are given. We also discuss the relation to the matrix model.
