On soft SUSY breaking parameters in string models with anomalous U(1) symmetry
Kawamura, Yoshiharu
Original · EN
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 more than of order m₃/₂² M².
