Glueball Masses from Linearly Confining Supergravity

Mass spectrum of 0++ glueballs is produced using a dual supergravity theory we proposed for pure N = 1 SU(N) gauge theory in four dimensions in the large N limit in the IR. The glueball states are expressed in terms of Whittaker functions. The spectrum is discrete and a function whose roots give the masses is written. The ratios of the masses are independent of the parameters of the theory and comparison to recent non-supersymmetric large N lattice QCD data available for the lowest three states shows agreement to within five percent
