Non-Supersymmetric Stable Vacua of M-Theory
نویسندگان
چکیده
We present a non-supersymmetric compactification of M-theory down to seven dimensions which is close to a stable non-supersymmetric vacuum. This compactification is dual to a non-supersymmetric interacting conformal field theory in six dimensions. We argue that a given classical compactification of M-theory or string theory is close to a stable vacuum if it is dual to a conformal field theory with no marginal operators (and in some cases with no exactly marginal operators only). The same argument applies to compactifications down to four dimensions.

Surviving on the Slope: Supersymmetric Vacuum in the Theories Where It Is Not Supposed to Be
In supersymmetric models with the runaway vacua or with the stable but non-supersymmetric ground state there exist stable field configurations (vacua) which restore one half of supersymmetry and are characterized by constant positive energy density. The formal foundation for such vacua is provided by the central extension of the N = 1 superalgebra with the infinite central charge.
متن کاملStable and Metastable Vacua in SQCD
We study deformations of N = 1 supersymmetric QCD that exhibit a rich landscape of supersymmetric and non-supersymmetric vacua.
متن کاملNon - supersymmetric Meta - Stable vacua in SU ( N ) SQCD with adjoint matter
We investigate models of SU(N) SQCD with adjoint matter and non trivial mesonic deformations. We apply standard methods in the dual magnetic theory and we find meta-stable supersymmetry breaking vacua with arbitrary large lifetime. We comment on the difference with known models.

متن کاملAnalytic Classes of Metastable de Sitter Vacua
In this paper, we give a systematic procedure for building locally stable dS vacua in N = 1 supergravity models motivated by string theory. We assume that one of the superfields has a Kähler potential of no-scale type and impose a hierarchy of supersymmetry breaking conditions. In the no-scale modulus direction the supersymmetry breaking is not small, in all other directions it is of order ǫ. W...
متن کاملDynamical Supersymmetry Breaking from Meta - stable Vacua in an N = 1 Supersymmetric Gauge Theory Masato Arai
We investigate supersymmetry breaking meta-stable vacua in N = 2, SU(2) × U(1) gauge theory with Nf = 2 massless flavors perturbed by the addition of small N = 1 preserving mass terms in a presence of a Fayet-Iliopoulos term. We derive the low energy effective theory by using the exact results of N = 2 supersymmetric QCD and examine the effective potential. At the classical level, the theory ha...
