- Title
Massive Hyper-Kähler Sigma Models and BPS Domain Walls.
- Authors
Arai, M.; Nitta, M.; Sakai, N.
- Abstract
With the non-Abelian hyper-Kähler quotient by U (M) and SU (M) gauge groups, we give the massive hyper-Kähler sigma models that are not toric in the N = 1 superfield formalism. The U(M) quotient gives N!/[M!(N – M)!] (N is the number of flavors) discrete vacua that may allow various types of domain walls, whereas the SU (M) quotient gives no discrete vacua. We derive a BPS domain-wall solution in the case of N = 2 and M = 1 in the U(M) quotient model.© 2005 Pleiades Publishing, Inc.
