Abstract:
We consider the heavy quark-antiquark potential in the AdS / QCD correspondence, extending recent calculations to a more general family of geometries. We show explicitly that Cornell-like behaviour is a consequence of this general geometry, provided certain conditions are satisfied. As an explicit example, we consider the application of our results to a recently calculated AdS-like metric deformed by back-reaction effects. We find that tuning the long-distance behaviour of the potential leads to a discrepancy at small distances, and discuss how to better constrain AdS / QCD geometries.- heavy quark
