Glueball spectrum for QCD from AdS supergravity duality
Year: 2000
Type: article
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: g2N→∞ . The bosonic fields in the supergravity multiplet lead to 6 independent wave equations contributing to glueball states with JPC=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.
