DBI skyrmion, high energy (large s) scattering and fireball production
  We analyze the high energy scattering of hadrons in QCD in an effective theory model inspired from a gravity dual description. The nucleons are skyrmion-like solutions of a DBI action, and boosted nucleons give pions field shockwaves necessary for the saturation of the Froissart bound. Nuclei are analogs of BIon crystals, with the DBI skyrmions forming a fluid with a fixed inter-nucleon distance. In shockwave collisions one creates scalar (pion field) ``fireballs'' with horizons of nonzero temperature, whose scaling with mass we calculated. They are analogous to the hydrodynamic ``dumb holes,'' and their thermal horizons are places where the pion field becomes apparently singular. The information paradox becomes then a purely field theoretic phenomenon, not directly related to quantum gravity (except via AdS-CFT).
