DBI skyrmion, high energy (large s) scattering and fireball production

TL;DR

This paper models high energy hadron scattering using a gravity-inspired effective theory with DBI skyrmions, predicting fireball formation with horizons and exploring the thermal and information-theoretic aspects of these phenomena.

Contribution

It introduces a novel effective theory model for high energy QCD scattering based on gravity duals, featuring DBI skyrmions and fireball horizons.

Findings

Fireballs with horizons form in shockwave collisions.

Scaling laws for fireball temperature and mass are derived.

The information paradox is interpreted within a field theory context.

Abstract

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).
