A fitted Killingbeck potential reproduces B, B_s, and B_c masses to under 0.5% for selected parameters, but its wavefunction at the origin is unreliable, inflating the B decay constant by up to 84%.

abstract
We report some approximate analytic form of meson wave function constructed upon solving Schrodinger equation with linear plus Coulomb type Cornell potential. With this wave function, we study Isgur-Wise function and its derivatives for heavy-light mesons in the infinite heavy quark mass limit. We also explore the elastic form factors, charge radii and decay constants of pseudoscalar mesons in this QCD inspired quark model approach.

Spectroscopic and Structural Properties of $B$, $B_s$, and $B_c$ Mesons within a Non-Relativistic Potential Model: A Comparative Analysis via Matrix Numerov and Variational Methods
A fitted Killingbeck potential reproduces B, B_s, and B_c masses to under 0.5% for selected parameters, but its wavefunction at the origin is unreliable, inflating the B decay constant by up to 84%.
