Beschreibung
We investigate the spectrum and wave functions of heavy mesons in terms
of the number of light flavours and mass, upon introducing a heavy quark
in the perturbative regime of the QCD conformal window. We then compute
the conformal Isgur-Wise function which is a central quantity of the
dynamics of heavy mesons. We further determine the impact of the
residual low energy confining dynamics. The impact of radiative
corrections and first-order mass corrections is discussed.
As a working framework, we adapt the heavy quark effective theory to the
perturbative conformal window dynamics. The investigation can be easily
extended to other gauge representations of the colour group and
multi-quark bound states.
Our work lays the foundations to systematically go beyond the infinite
mass defect approximation in conformal field theories. Furthermore, our
results can be used when constructing bright or dark extension of the
Standard Model, for example dark matter models featuring dark mesons.
