Enhancing the Jet Quenching Parameter from Marginal Deformations
Justin F. Vazquez-Poritz
TL;DR
This paper investigates how marginal deformations in a supersymmetric gauge theory can enhance the jet quenching parameter, addressing discrepancies between theoretical predictions and experimental data in heavy-ion collisions.
Contribution
It demonstrates that marginal deformations in N=4 SYM can significantly increase the jet quenching parameter, providing a potential explanation for experimental observations.
Findings
Marginal deformations can enhance the jet quenching parameter q.
The enhancement depends on the string endpoints' positions in internal space.
Results suggest a pathway to reconcile theory with RHIC data.
Abstract
A number of recent papers have applied the AdS/CFT correspondence to a strong-coupling calculation of the medium-induced radiative parton energy loss in nucleus-nucleus collisions at RHIC. The predicted value of the "jet quenching parameter" q, however, is rather small compared to the experimental results. For hot N=4 supersymmetric Yang-Mills theory, certain marginal deformations can have the effect of enhancing q. This result is highly sensitive to the location of the fundamental string's endpoints in the internal space.
