Abstract: (arXiv)
We present the analysis of the complete glueball spectrum for the AdS7AdS^7 black hole supergravity dual of QCD4QCD_4 in strong coupling limit: g2Ng^2 N \to \infty. The bosonic fields in the supergravity multiplet lead to 6 independent wave equations contributing to glueball states with JPC=2++,1+,1J^{PC} = 2^{++},1^{+-}, 1^{--}, 0++0^{++} and 0+0^{-+}. We study the spectral splitting and degeneracy patterns for both QCD4QCD_4 and QCD3QCD_3. Despite the expected limitations of a leading order strong coupling approximation, the pattern of spins, parities and mass inequalities bear a striking resemblance to the known QCD4QCD_4 glueball spectrum as determined by lattice simulations at weak coupling.
