Query: The mass of heavy-light mesons in a constituent quark picture with
  partially restored chiral symmetry   We probe effects of the partial chiral symmetry restoration to the mass of
heavy-light mesons in a constituent quark model by changing the constituent
quark mass of the light quark. Due to the competing effect between the quark
mass and the linearly rising potential, whose contribution to the energy
increases as the quark mass decreases, the heavy-light meson mass has a minimum
value near the constituent quark mass typically used in the vacuum. Hence, the
meson mass increases as one decreases the constituent quark mass consistent
with recent QCD sum rule analyses, which show an increasing $D$ meson mass as
the chiral order parameter decreases.
