- Abstract
J pc = 0 + + and 2 + + states of all charm tetraquark ( [ c c ] [ c ¯ c ¯ ] ) are investigated in the framework of non-relativistic QCD using diquark-antidiquark coulomb plus power potential of the type V d d ¯ = k s α s r + A r ν with power index ν varying from 0.1 to 2. We have included the spin hyperfine interaction to obtain masses of J pc = 0 + + and 2 + + states of all charm tetraquark. We have computed branching ratios and decay widths of the main, hidden and open charm channels of tetraquark state with the help of the potential model parameters, masses and the respective radial wave function obtained by our non-relativistic quark model. Our theoretical predictions of the masses as well as the branching ratios and decay widths at power index ν =1 are found to be in good accordance with other available theoretical predictions.
