Description
Upon introducing a heavy quark in the perturbative regime of the QCD conformal
window we precisely determine the associated heavy meson spectrum and wave
functions in terms of the number of light flavours and mass. We then compute the
conformal Isgur-Wise function which is a central quantity in heavy quark physics.
We further determine the impact of the residual low energy confining dynamics on
the heavy meson spectrum. As a working framework, we adapt the heavy quark
effective theory to the perturbative conformal window dynamics. Our work lays the
foundations to systematically go beyond the infinite mass defect approximation in
conformal field theories.
