Fayet-Iliopoulos D-terms, neutrino masses and anomaly mediated supersymmetry breaking
We explore, in the context of the MSSM generalised to admit massive
neutrinos, an extension of the Anomaly Mediated Supersymmetry Breaking solution
for the soft scalar masses to incorporate Fayet-Iliopoulos D-terms. The slepton
mass problem characteristic of the scenario is resolved, and the fermion mass
hierarchy is explained via the Froggatt-Nielsen mechanism. FCNC problems are
evaded by a combination of universal doublet charges and Yukawa textures which
are diagonalised by transforming the left-handed fields only.Comment: 13 pages, TeX, Uses Harvmac (big). Improved R-parity discussion (v2).
