Abstract

The infrared attractiveness of soft-supersymmetry breaking (SSB) parameters is investigated in extra dimensions. The SSB parameters are assumed to run from the Planck scale M_PL down to the GUT scale M_GUT. We find that, even for M_PL/M_GUT=100, the SSB parameters in six dimensions can align out of their anarchical disorder at M_PL in such a way that flavor-changing neutral currents as well as dangerous CP-violating phases are sufficiently suppressed at M_GUT. A concrete, realistic example based on SU(5) in six dimensions is presented.
