Holographic Description of Heavy-Quark Potentials in an Inflationary Braneworld Scenario

Abstract

We study heavy-quark potential in an inflationary braneworld scenario. The scenario we consider is an (Euclidean) inflating braneworld $Ad{S}_4$ embedded in a static Euclidean $Ad{S}_5$. Using gauge/gravity duality we obtain a confining phase depending on the ratio between the Hubble parameter $H$ in the braneworld and the brane tension $\sigma$.
