Computation of decay constant and digluon decay width of Charmonia

摘要

The hydrogen like wave function has been used for computation of the mass spectrum and decay properties of charmonium within the framework of phenomenological quark antiquark coulomb plus power potential model. Potential interaction index v is varied from 0.5 to 2.0. The spin-spin hyperfine interaction in considered to incorporate splitting of the ground and excited state energy levels. Further, spin-orbit and tensor interactions computed for excited states. Using the extracted normalized reduced wave function, the decay constant and digluon decay widths have been calculated.
