title = "Higgsino mass matrix ansatz for MSSM",

abstract = "An ansatz, Det M{\=H} = 0, for the Higgsino mass matrix is suggested toward the minimal supersymmetric standard model (MSSM). Small instanton solutions effective around the GUT scale can fulfill this condition. An argument that the couplings contain a moduli field is given for a dynamical realization of this Higgsino mass matrix ansatz. We also present a string orbifold trinification toward this realization.",
