Holographic Pomeron and Schwinger Mechanism
I revisit the problem of dipole-dipole scattering via exchanges of soft Pomerons in the context of holographic QCD and show that a single closed string exchange contribution to the eikonalized dipole-dipole scattering amplitude yields a Regge behavior of the elastic amplitude. Furthermore the Regge behavior can be understood as a result of string creation through Schwinger mechanism where the longitudinal electric field is due to the relative rapidity of the scattering dipoles. The corresponding Unruh radiation of the accelerated string implies the existence of a "micro-fireball'' in the middle of the transverse space, which may be at the origin of the thermal character of multiparticle production in ep/pp collisions.
