We obtain the spectrum of glueball masses for the N = 1 nonconformal cascad
e theory whose supergravity dual was recently constructed by Klebanov and S
trassler. The glueball masses are calculated by solving the supergravity eq
uations of motion for the dilaton and the two-form in the deformed conifold
background. (C) 2001 Elsevier Science B.V. All rights reserved.
