Holographic Mesons in D4/D6 Model Revisited

초록

We revisit holographic mesons in the D4/D6 model to study holographic light vector, mesons and the properties of heavy quarkonium in a confining phase. To treat light mesons and the heavy quarkonium on the same footing, we use the same compactification scale, M-KK, in both systems. We observe that like scalar and pseudo-scalar mesons, the vector meson mass is linearly proportional to the square root of the quark mass when the quark mass is large. With M-KK fixed by the light meson masses, we calculate the mass of the heavy quarkonium in a confining phase. In order to describe the heavy quarkonium in the D4/D6 model, we consider the classical open string configuration.
