We calculate the area of a marginally trapped surface formed by a head-on collision of gravitational shock waves in AdS_D. We use this to obtain a lower bound on the entropy produced after the collision. A comparison to entropy production in heavy ion collisions is included. We also discuss an O(D-2) remnant of conformal symmetry which is present in a class of gravitational shock wave collisions in AdS_D and which might be approximately realized (with D=5) in central heavy-ion collisions.

Tensor spin polarization induced by curved freeze-out hypersurface
The curvature of the freeze-out hypersurface induces a tensor spin polarization of vector mesons at leading gradient order, with predicted phi-meson spin alignment around -10^-4 to -10^-3.

Entropy production in pp and Pb-Pb collisions at energies available at the CERN Large Hadron Collider
From LHC data on particle spectra and femtoscopic radii, the entropy per unit rapidity is determined for pp and Pb-Pb collisions, and simulations trace about 95% of that entropy to the first fm/c.
