Query: New Regimes of Stringy (Holographic) Pomeron and High Multiplicity pp
  and pA Collisions   Holographic AdS/QCD models of the Pomeron unite a string-based description of
hadronic reactions of the pre-QCD era with the perturbative BFKL approach. The
specific version we will use due to Stoffers and Zahed, is based on a
semiclassical quantization of a "tube" (closed string exchange or open string
virtual pair production) in its Euclidean formulation using the scalar Polyakov
action. This model has a number of phenomenologically successful results. The
periodicity of a coordinate around the tube allows the introduction of a
Matsubara time and therefore an effective temperature Teff on the string. We
observe that at the LHC energies and for sufficiently small impact parameter,
Teff approaches and even exceeds the Hagedorn temperature of the QCD strings.
Based on studies of the stringy thermodynamics of pure gauge theories we
suggest that there should exist two new regimes of the Pomeron: the
"near-critical" and the "post-critical" ones. In the former one, string
excitations create a high entropy "string ball", with high energy and entropy
but small pressure/free energy. If heavy enough this ball becomes a (dual)
black hole (BH). As the intrinsic temperature of the string exceeds the
Hagedorn temperature, the ball becomes a post-critical explosive "QGP ball".
The hydrodynamical explosion resulting from this scenario was predicted by us
to have radial flow exceeding that ever seen even in heavy ion collisions,
which was recently confirmed by CMS and ALICE at LHC. We also discuss the
elastic scattering profile, finding some hints for new phases in it, as well as
two-particle correlations.
