Charmonium Mass Spectrum with Spin-Dependent Interaction in Momentum-Helicity Space

Abstract EN

In this paper we have solved the nonrelativistic form of the Lippmann-Schwinger equation in the momentum-helicity space by inserting a spin-dependent quark-antiquark potential model numerically.

To this end, we have used the momentum-helicity basis states for describing a nonrelativistic reduction of one-gluon exchange potential.

Then we have calculated the mass spectrum of the charmonium ψcc¯, and finally we have compared the results with the other theoretical results and experimental data.
