But the situation is different for QCD, one reason is that the loop effects are more significant because $\\alpha_s$ is much larger than $\\alpha$, and secondly the non-perturbative QCD effects may induce a sizable scalar potential. In this work, we phenomenologically study the contribution of the scalar potential to the spectra of charmonia, bottomonia and $b\\bar c(\\bar b c)$ family.
