Glueball Masses from Linearly Confining Supergravity    [PDF]

Girma Hailu

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.
