Strong coupling expansion for Pomeron intercept in QCD4 derived

Abstract

We briefly review the approach for strong coupling calculation of glueball masses based on the duality between supergravity and Yang-Mills theory. Earlier work is extended to non-zero spin. Fluctuations in the gravitational metric lead to the $2^{++}$ tensor glueball state on the leading Pomeron trajectory with a mass relation: $m(0^{++}) < m(2^{++}) $. In particular, for $QCD_4$, a strong coupling expansion for the Pomeron intercept is obtained.
