Series solutions to theN-dimensional radial Schrödinger equation for the quark–antiquark interaction potential

In this work, we analytically obtain the energy eigenvalues and normalized eigenfunctions of the radial Schrödinger equation in N -dimensional Hilbert space for the quark–antiquark interaction potential using the power series technique via a suitable ansatz to the wavefunction. From the energy eigenvalues, the mass spectra of heavy quarkonia in three dimensions are obtained. The problem is also solved numerically. The obtained analytical and numerical results are in good agreement with the existing results.
