Holographic Three-Jet Events in Strongly Coupled N=4 Yang-Mills Plasma

Understand

We analyse classical string configurations with non-trivial transverse dynamics in $AdS_5$-Schwarzschild.

• These strings develop kink-like structures which, via the gauge/gravity duality, can be interpreted as the propagation of hard gluons produced in association with a quark-antiquark pair in a strongly coupled $\mathcal{N}=4$ SYM plasma.
• We observe the appearance of two physically distinct regimes of the in-plasma dynamics, depending on whether the medium is able to resolve the transverse structure of the string prior to its total quench.
• From these studies we extract the medium resolution scale of the strongly coupled SYM plasma, defined as the smallest angular separation between two jets that the medium can resolve, $\theta_{\rm res} = \mathcal{C}_{\rm res} ( E /\sqrt{\lambda} T)^{-2/3}$, where $\mathcal{C}_{\rm res}= \frac{2^{4/3}}{\pi}\frac{\Gamma(3/4)^2}{\Gamma(5/4)^2}$.
