  We calculate the energy of a static string in an AdS slice between two
D3-branes with orbifold condition. The energy for configurations with endpoints
on a brane grows linearly for large separation between these points. The
derivative of the energy has a discontinuity at some critical separation.
Choosing a particular position for one of the branes we find configurations
with smooth energy. In the limit where the other brane goes to infinity the
energy has a Coulombian behaviour for short separations and can be identified
with the Cornell potential for a quark anti-quark pair. This identification
leads to effective values for the AdS radius, the string tension and the
position of the infrared brane. These results suggest an approximate duality
between static strings in an AdS slice and a heavy quark anti-quark
configuration in a confining gauge theory.
