摘要：

Motivated by the mu-problem and the axion solution to the strong CP-problem, we extend the MSSM with one more chiral singlet field X-ew. The underlying PQ-symmetry allows only one more renormalizable term XewHuHd in the superpotential. The spectrum of the Higgs system includes a light pseudoscalar a(X) (in addition to the standard CP-even Higgs boson), predominantly decaying to two photons: a(X) -> gamma gamma. Both Higgs bosons might be in the range accessible to current LHC experiments.
