# Supergravity and the jet quenching parameter in the presence of R-charge densities

@article{Avramis2006SupergravityAT, title={Supergravity and the jet quenching parameter in the presence of R-charge densities}, author={Spyros D. Avramis and Konstadinos Sfetsos}, journal={Journal of High Energy Physics}, year={2006}, volume={2007}, pages={065-065} }

Following a recent proposal, we employ the AdS/CFT correspondence to compute the jet quenching parameter for = 4 Yang-Mills theory at nonzero R-charge densities. Using as dual supergravity backgrounds non-extremal rotating branes, we find that the presence of the R-charges generically enhances the jet quenching phenomenon. However, at fixed temperature, this enhancement might or might not be a monotonically increasing function of the R-charge density and depends on the number of independent…
