  We have investigated the properties of quarkonium states in an anisotropic
hot QCD medium by correcting the full Cornell potential, not the Coulomb term
alone as usually done in the literature, with a dielectric function from the
hard-loop resummed gluon propagator. We have found that in-medium modification
in anisotropic medium causes less screening than in isotropic medium. In the
short distance limit, potential does not show any medium dependence whereas in
the long-distance limit, it reduces to the Coulomb potential with a dynamically
screened color charge. In addition, anisotropy in momentum space introduces a
characteristic angular dependence in the potential and as a result, quarkonium
states in anisotropic medium are more tightly bound than in isotropic medium.
In particular, quark pairs aligned in the direction of anisotropy are more
bound than perpendicular to the direction of anisotropy.
