BOSON BOUND-STATES NEAR A KERR-NEWMAN NAKED SINGULARITY

We discuss boson bound states near a Kerr-Newman (KN) naked singularity by means of spectroscopic eigenvalue analysis. The results show that in the background of a KN naked singularity, the self-conjugate extension operator of a boson Hamiltonian has and only has discrete eigenvalues. The discrete eigenvalues exist in the interval (-mu, mu). Thus, we find that the boson bound states may appear only for mu not-equal 0. Here mu is the boson mass.
