Holographic mesons in D4/D6 model revisited

Understand

We revisit holographic mesons in the D4/D6 model to study holographic light vector mesons and the properties of heavy quarkonium in confining and deconfining phases.

• To treat the light mesons and heavy quarkonium on the same footing, we use the same compactification scale MKK 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 a MKK fixed by light meson masses, we calculate the mass of heavy quarkonium in confining and deconfining phases.
