Query: Soft scalar masses in supergravity with horizontal U(1)_X gauge symmetry   In supergravity with modular invariance and horizontal $U(1)_X$ gauge
symmetry there is a relation between modular weights and $U(1)_X$ charges. The
soft scalar masses are then strongly correlated with Yukawa matrices. The
implications for FCNC are discussed.
