Glueball spectrum for QCD from AdS supergravity duality
Abstract
We present the analysis of the complete glueball spectrum for the AdS ^{7} black hole supergravity dual of QCD _{4} in strong coupling limit: g^{2}N→∞ . The bosonic fields in the supergravity multiplet lead to 6 independent wave equations contributing to glueball states with J^{PC}=2 ^{++},1 ^{+},1 ^{} , 0 ^{++} and 0 ^{+} . We study the spectral splitting and degeneracy patterns for both QCD _{4} and QCD _{3} . Despite the expected limitations of a leading order strong coupling approximation, the pattern of spins, parities and mass inequalities bare a striking resemblance to the known QCD _{4} glueball spectrum as determined by lattice simulations at weak coupling.
