Investigation of decay widths of charmed hadrons

Abstract The annihilation and radiative decay widths of fully charmed hadrons are investigated using a non-relativistic phenomenological potential model. The wavefunctions and model parameters obtained by solving the non-relativistic Schrodinger equation are used to calculate the various decay widths. The annihilation decay widths of charmonium, radiative decay widths of charmonium and triply charmed baryons are evaluated. It is seen that the radiative decays of charmonium are dominated by E 1 and M 1 transitions, whereas for triply charmed baryons the radiative decays are dominated by E 2 and M 1 transitions.
