Query: Pomeron Interactions from the Einstein-Hilbert Action   Holographic models of QCD, collectively known as AdS/QCD, have been proven
useful in deriving several properties of hadrons. One particular feature well
reproduced by such models is the Regge trajectories, both for mesons and
glueballs. We focus on scalar and tensor glueballs, and derive an effective
theory for the Pomeron by analytic continuation along the leading trajectory
from the tensor glueball. It then follows that the Pomeron, as the tensor
glueball itself, should possess a two-index polarization tensor, inherited from
the graviton. The three-graviton interaction is deduced from the
Einstein-Hilbert action. Using this structure in the cross section of
double-Pomeron production of the tensor glueball, we calculate certain angular
distributions of production and compare them with those from the CERN WA102
experiment. We find that the agreement is very good for the $f_2(2300)$ tensor
glueball candidate. At the same time, other tensor states -- such as
$f_2(1270)$ and $f'_2(1520)$ -- have completely different distributions, which
we interpret as consequence of the fact that they are not glueballs and thus,
in our model, unrelated to the gravitational excitations, which are dual to
spin-2 glueballs.
