Holographic Mesons in D4/D6 Model Revisited

Abstract
We revisit holographic mesons in the D4/D6 model to studyholographic light vector mesons and the properties of heavyquarkonium in confining phase. To treat the light mesons and heavyquarkonium on the same footing, we use the same compactificationscale MKK in both systems. We observe that like scalar andpseudo-scalar mesons the vector meson mass is linearly proportionalto the square root of the quark mass, when the quark mass is large.With a MKK fixed by light meson masses, we calculate the massof heavy quarkonium in confining phase. In order to describe theheavy quarkonium in the D4/D6 model, we consider classical openstring configuration.
