We point out that the μproblem in theories in which
supersymmetry breaking
is communicated to the observable sector by gauge interactions is more severe than the one encountered in the conventional gravitymediated scenarios. The difficulty is that once μ is generated by a oneloop diagram, then usually Bμ is also generated at the same loop order. This leads to the problematic relation Bμtμ wheret 10–100 TeV is the effective supersymmetrybreaking scale. We 0 present a class of theories for which this problem is naturally solved. Here, without any fine tuning among parameters, μ is generated at one loop, while Bμ arises only at the twoloop level. This mechanism can naturally lead to an interpretation of the Higgs doublets as pseudoGoldstone bosons of an approximate global symmetry.

Indeed, if the SUSY breaking hidden sector and the visible (MSSM) sector are only connected via gauge interactions, as was suggested for a denition of General Gauge Mediation (GGM) [ 3], the B term, which violates the U(1)PQ PecceiQuinn symmetry, cannot be generated, since this U(1)PQ is preserved by gauge interactions...
