The gauge-string duality and heavy ion collisions

TL;DR

This paper reviews how gauge-string duality helps understand heavy ion collisions, focusing on heavy quark energy loss and speculating on black hole formation models, bridging physics with philosophical perspectives.

Contribution

It provides a non-technical overview of applying gauge-string duality to heavy ion collisions and introduces novel ideas on black hole dynamics via string models.

Findings

Trailin string calculations elucidate heavy quark energy loss.

Speculative models connect string theory to black hole formation.

The review bridges physics and philosophy of science.

Abstract

I review at a non-technical level the use of the gauge-string duality to study aspects of heavy ion collisions, with special emphasis on the trailing string calculation of heavy quark energy loss. I include some brief speculations on how variants of the trailing string construction could provide a toy model of black hole formation and evaporation. This essay is an invited contribution to "Forty Years of String Theory" and is aimed at philosophers and historians of science as well as physicists.
