Holographic Heavy Quark Symmetry

Understand

We investigate the heavy quark spin symmetry, i.e.

• the mass degeneracy of pseudo-scalar and vector quarkonia at heavy quark limit, by using the gauge/gravity correspondence.
• We allow generic D3-like geometry with a flavor D7-brane, to avoid supersymmetric mass degeneracy.
• For geometries admitting physical QCD-like properties, we find that the mass degeneracy is generically achieved in a good accuracy, up to a few percent mass splitting.
