We acknowledge interesting discussions on the subject with A. Gotsman, Yu. Kovchegov, U. Maor, M. Praszalowicz, and D. T. Son. We are indebted to T. D. Lee for valuable comments and suggestions, and to H. Meyer and P. Petreczky for a discussion of the lattice data on glueballs. The work of D. K. and K. T. was supported by the U.S. Department of Energy under Contract No. DE-AC02-98CH10886. This research was supported in part by the GIF Grant No. I-620-22.14/1999 and by the Israeli Science Foundation, founded by the Israeli Academy of Science and Humanity. In the early stage of the work of K. T. was sponsored by the U.S. Department of Energy under Grant No. DE-FG03-00ER41132.

N2 - We construct an effective low energy Lagrangian using constraints imposed by the renormalization group. Degrees of freedom are gluons and a scalar glueball. This effective theory has a dual description as classical gluodynamics on a curved conformal background. Color fields are dynamically confined, and the strong coupling freezes at distances larger than the glueball size. We make specific predictions (in particular, on the Nc dependence of glueball properties) which can be tested in lattice simulations of gluodynamics.
