Role of the Anomalous $U(1)_A$ for the Solution of the Doublet-Triplet Splitting Problem via the Pseudo-Goldstone Mechanism
The anomalous U(1)_A symmetry provides a generic method of getting accidental symmetries. Therefore, it can play a crucial role in solving the doublet-triplet splitting and the \mu-problems via the `pseudo-Goldstone' mechanism: U(1)_A can naturally uncorrelate the two grand unified Higgs sector...
