The continuous line represents the result from light-front holography modified for pQCD effects using Eq. (11) and transformed to the V scheme using the extrapolated CSR results shown in Fig. 4. The continuous band is the JLab results transformed to the V scheme using the same CSR. The dashed line is the Cornell potential. The inserted figure zooms into the deep UV domain. PQCD results at two loops (Peter, Ref. [61]) and three loops (Anzai et al. , Ref. [62]) are shown, respectively, by the cross-hatched band and the dot-dashed line. An arbitrary offset is applied to the Anzai et al. results. In the case of heavy quarks the light-front holographic equations reduce to a nonrelativis- tic Schr¨ odinger equation in configuration space with potential where V$_{conf}$ for a soft-wall dilaton background is the potential for a three-dimensional har- monic oscillator, V$_{conf}$ ≃ 1 $_{2}$m$_{red}$ ω $^{2}$r$^{2}$. Here m$_{red}$ is the reduced mass of the heavy Q − Q V ( r ) = − 4 3 α$_{V}$ ( r ) r + V$_{conf}$ ( r ) , (20) 21
