From black holes to glueballs: The QCD(3) tensor glueball at strong coupling

A strong coupling-calculation of glueball masses based on the duality betwe en supergravity and Yang-Mills theory is presented. Earlier work is extende d to non-zero spin. Fluctuations in the gravitational metric lead to the 2( ++) state on the leading Pomeron trajectory with a mass relation: m(0(++)) < m(2(++)) < m(1(-+)). Contrary to expectation, the mass of our new 0(++) s tate (m(2) = 5.4573) associated with the graviton is smaller than the mass of the (0) over tilde(++) state(m(2) = 11.588) from the dilaton, which in f act is exactly degenerate with the tensor 2(++).
