Abstract

The production of ηc in two-photon γγ fusion reaction at CLEO was investigated. The spin dependence of Cornell potential along with spin-orbit, spin-spin and tensor components was assumed to occur from the vector Coulombic part. The confinement potential was assumed to be scalar with minimal spin-orbit contribution which was observed due to Thomas precession. The production via two-photon fusion and four-charged particles was ensured by total transverse momentum.
