The $\mu$-Problem and Seesaw-type Mechanism in the Higgs Sector
  We explore a new solution to the $\mu$-problem. In the scenario of SUSY-breaking mediation through anti-generation fields, we find that the $B\mu$ term has its origin in a seesaw-type mechanism as well as in a loop diagram through gauge interactions. It is shown that the dominant contributions to the $B\mu$ term are controlled by the flavor symmetry in the model.
