“…As stated before in [59][60][61][62][63][64][65][66][67][68][69][70][71][72][73], for any fixed n the computed energies become more convergent as l increases. This is expected since the expansion parameter 1/N or 1/k becomes smaller as l becomes larger since the parameter k is proportional to n and appears in the denominator in higher-order correction.…”

We give a review and present a comprehensive calculation for the leptonic constant f Bc of the low-lying pseudoscalar and vector states of B c -meson in the framework of static and QCD-motivated nonrelativistic potential models taking into account the one-loop and two-loop QCD corrections in the short distance coefficient that governs the leptonic constant of B c quarkonium system. Further, we use the scaling relation to predict the leptonic constant of the nS-states of the bc system. Our results are compared with other models to gauge the reliability of the predictions and point out differences.

“…Our aim is to derive analytically the exact energy spectrum for a moving particle in the presence of the potential (12). We begin by considering the SE in arbitrary dimensions D for our proposed potential [30,31,[76][77][78][79][80][81][82][83][84][85][86][87][88][89][90] …”

Abstract:A new non-central potential, consisting of a pseudoharmonic potential plus another recently proposed ringshaped potential, is solved. It has the formThe energy eigenvalues and eigenfunctions of the bound-states for the Schrödinger equation in D-dimensions for this potential are obtained analytically by using the Nikiforov-Uvarov method. The radial and angular parts of the wave functions are obtained in terms of orthogonal Laguerre and Jacobi polynomials. We also find that the energy of the particle and the wave functions reduce to the energy and the wave functions of the bound-states in three dimensions. PACS
