MSSM scenarios with a light CP-odd Higgs boson

MSSM scenarios with a light CP-odd Higgs boson

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 pro...
