The possibility of the presence of a light pseudoscalar with the mass of 28 GeV in the MSSM Higgs sector extended by dimension-six operators is analyzed. The perturbative unitarity and vacuum stability constraints are discussed. Tree-level production cross sections of a light pseudoscalar in the process gg → µµbb−, and cross sections of a light pseudoscalar production in the topquark decay are evaluated for suitable benchmark points.
