Model-independent analysis of soft masses in heterotic string models with anomalous U(1) symmetry
نویسنده
چکیده
We study the magnitudes of soft masses in heterotic string models with anomalous U(1) symmetry model-independently. In most cases, D-term contribution to soft scalar masses is expected to be comparable to or dominant over other contributions provided that supersymmetry breaking is mediated by the gravitational interaction and/or an anomalous U(1) symmetry and the magnitude of vacuum energy is not more than of order m3/2M 2. ∗e-mail: [email protected]

On Soft Susy Breaking Parameters in String Models with Anomalous U(1) Symmetry
We study the magnitudes of soft SUSY breaking parameters in heterotic string models with anomalous U(1) symmetry. In most cases, D-term contribution to soft scalar masses is expected to be comparable to or dominant over other contributions provided that supersymmetry breaking is mediated by the gravitational interaction and/or an anomalous U(1) symmetry and the magnitude of vacuum energy is not...
متن کاملSoft Scalar Masses in String Models with Anomalous U(1) symmetry
We obtain the low-energy effective theory from string models with anomalous U(1) symmetry. The feature of soft supersymmetry breaking scalar masses and some phenomenological implications are discussed. We show that it is, in general, difficult to keep the degeneracy and the positivity of squared soft scalar masses at the Planck scale. e-mail: [email protected] Alexander von Humboldt...
متن کاملModuli Stabilization in non-Supersymmetric Minkowski Vacua with Anomalous U(1) Symmetry
We study how two moduli can be stabilized in a Minkowski/de Sitter vacuum for a wide class of string-inspired Supergravity models with an effective Fayet-like Supersymmetry breaking. It is shown under which conditions this mechanism can be made natural and how it can give rise to an interesting spectrum of soft masses, with a relatively small mass difference between scalar and gaugino masses. I...
متن کاملAnomalous U(1) Gauge Symmetries and Heterotic - Type I/ii String Duality∗
Anomalous U(1) gauge symmetries can appear both in heterotic and type I string theories. In the heterotic case we find a single anomalous U(1), while in open string theories several such symmetries can appear. Nonetheless, there is a conjectured duality symmetry that might connect these two theories. We review the properties of anomalous gauge symmetries in various string theories as well as th...
متن کاملImplications of Anomalous U ( 1 ) Symmetry in Unified Models : the Flipped SU ( 5 ) × U ( 1 ) Paradigm
A generic feature of string-derived models is the appearance of an anomalous Abelian U (1) A symmetry which, among other properties, constrains the Yukawa couplings and distinguishes the three families from each other. In this paper, we discuss in a model-independent way the general constraints imposed by such a U (1) A symmetry on fermion masses, R-violating couplings and proton-decay operator...
