Holographic Pomeron and Primordial Viscosity    [PDF]

Ismail Zahed

The holographic pomeron in dipole-dipole scattering follows from the exchange of a stringy instanton with an apparent Unruh temperature and entropy that are caused by the rapidity gap $\chi$ of the collision. We show that the primordial transverse shear viscosity to transverse entropy density ratio is $\eta_\perp/s_\perp=(\pi k/\chi)^2/4\pi$ for dipole sources of N-ality k. The primordial holographic matter released by the pomeron is an ideal fluid at asymptotic rapidity $\chi$.
