Partial Breaking of N = 2 Supersymmetry and of Gauge Symmetry in the U ( N ) Gauge Model

چکیده
We explore vacua of the U (N) gauge model with N = 2 supersymmetry recently constructed in hep-th/0409060. In addition to the vacuum previously found with unbroken U (N) gauge symmetry in which N = 2 supersymmetry is partially broken to N = 1, we find cases in which the gauge symmetry is broken to a product gauge group n i=1 U (N i). The N = 1 vacua are selected by the requirement of a positive definite Kähler metric. We obtain the masses of the supermultiplets appearing on the N = 1 vacua.

U(n) Gauge Model and Partial Breaking of N = 2 Supersymmetry
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 considered by Antoniadis, Patouche and Taylor. We discuss the conditions on the vacua of the model with partial super-symmetry breaking.

Non-commutative field theory as a theory including the Lorentz violation can be constructed in two different ways. In the first method, the non-commutative fields are the same as the ordinary ones while the gauge group is restricted to U(n). For example, the symmetry group of standard model in non-commutative space is U(3)×(2)×U(1) which can be reduced to SU(3)×SU(2)×U(1) by two appropriate spo...
متن کاملSpontaneous Partial Breaking of N = 2 Supersymmetry and the U ( N ) Gauge Model
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.
متن کاملPartial Breaking of N = 2 Supersymmetry and Decoupling Limit of Nambu - Goldstone Fermion in U ( N ) Gauge Model
We study the N = 1 U (N) gauge model obtained by spontaneous breaking of N = 2 supersymmetry. The Fayet-Iliopoulos term included in the N = 2 action does not appear in the resulting N = 1 action and the superpotential is modified to break discrete R symmetry. We take a limit in which the Kähler metric becomes flat and the superpotential preserves non-trivial form. The Nambu-Goldstone fermion is...
متن کاملSupersymmetric U ( N ) Gauge Model and Partial Breaking of N = 2 Supersymmetry
Guided by the gauging of U (N) isometry associated with the special Kähler geometry , and the discrete R symmetry, we construct the N = 2 supersymmetric action of a U (N) invariant nonabelian gauge model in which rigid N = 2 supersymmetry is spontaneously broken to N = 1. This generalizes the abelian model considered by Antoniadis, Patouche and Taylor. We shed light on complexity of the supercu...
