Abstract
We investigate the heavy quark spin symmetry ie the mass degeneracy of pseudoscalar and vector quarkonia at heavy quark limit by using the gauge/gravity correspondence We allow generic D3like geometry with a flavor D7brane to avoid supersymmetric mass degeneracy For geometries admitting physical QCDlike properties we find that the mass degeneracy is generically achieved in a good accuracy up to a few percent mass splitting We also compute spectra of excited quarkonia states and discuss comparisons with experiments and quarkmodel calculationsThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
