Light CP-odd Higgs boson production associated with the J/psi meson in the NMSSM

Abstract

We explore production of a light CP-odd Higgs boson, a, associated with the J/psi meson in the next-to-minimal supersymmetric model. This model may resolve the little hierarchy problem of the minimal supersymmetric standard model by avoiding the bound of the SM-like Higgs boson mass from the Large Electron-Positron Collider (LEP) data with a large branching ratio of h --> aa. This work is a study of the light CP-odd Higgs boson production supplementary to that in the decay of Gamma into a and gamma. We expect to investigate this process at the future super B factory.
