We derive formula of soft supersymmetry breaking scalar masses from 4-dimensional string models within a more generic framework. We consider effects of extra gauge symmetry breakings including an anomalous U(1) breaking through flat directions, that is, D-term and F-term contributions, particle mixing effects and heavy-light mass mixing effects. Some phenomenological implications are discussed based on our mass formula.

Model-independent analysis of soft masses in heterotic string models with anomalous U(1) symmetry
Abstract 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 toExpand
Soft supersymmetry breaking terms from A(4) lepton flavor symmetry
We study the supersymmetric model with the A4 lepton flavor symmetry, in particular soft supersymmetry breaking terms, which are predicted from the A4 lepton flavor symmetry. We evaluate soft sleptonExpand
General soft terms from Supergravity including D-terms
We derive general expressions for soft terms in supergravity where D-terms contribute significantly to the supersymmetry breaking. Such D-terms can produce large splitting between scalar andExpand
More about soft terms and FCNC in realistic string constructions
In realistic four-dimensional string constructions the presence of anomalous U(1)'s is generic. In addition, the associated Fayet-Iliopoulos contribution to the D-term can break the extra gaugeExpand
String-derived D4 flavor symmetry and phenomenological implications
In this paper we show how some flavor symmetries may be derived from the heterotic string, when compactified on a 6D orbifold. In the body of the paper we focus on the D{sub 4} family symmetry,Expand
Constraints from F and D supersymmetry breaking in general supergravity theories
We study the conditions under which a generic supergravity model involving chiral and vector multiplets can admit vacua with spontaneously broken supersymmetry and realistic cosmological constant. WeExpand
RG-invariant sum rule in a generalization of anomaly-mediated SUSY-breaking models
We study a generalization of anomaly-mediated supersymmetry breaking (AMSB) scenarios, under the assumption that the effects of the high-scale theory do not completely decouple and D-term typeExpand
Superheavy supersymmetry from scalar mass ??? A parameter fixed points
Abstract In supersymmetric models, the well-known tension between naturalness and experimental constraints is relieved if the squarks and sleptons of the first two generations are superheavy, withExpand
Supersymmetry breaking and moduli stabilization with anomalous U(1) gauge symmetry
We examine the effects of anomalous U(1)A gauge symmetry on soft supersymmetry breaking terms while incorporating the stabilization of the modulus-axion multiplet responsible for the Green-SchwarzExpand
Charge and Color Breaking and D-terms in String Theory
In four dimensional superstring models, the gauge group normally contains extra U(1)s that are broken at a high energy scale. We show that the presence of the extra U(1)s is crucial for theExpand
