AdS to lowest order
and at short distances is given by

V(r)  →  - Q / r   +   (Qω2/2) r

which is the funnel-type potential.

Nevertheless,
the AdS spectrum is
harmonic-oscillator like.

Hence the lowest order terms
from Lattice QCD
do not necessarily dictate
the spectrum of the
quark-antiquark
propagator.
