Near Zone Hydrodynamics of AdS/CFT Jet Wakes

چکیده
The energy-momentum tensor of a supersonic heavy quark jet moving through a strongly-coupled N = 4 SYM plasma is analyzed in terms of first-order Navier-Stokes hydrodynamics. We focus on the near zone “head” region close to the heavy quark where deviations from hydrodynamic behavior are expected to be large. For realistic quark velocities, v = 0.99, we find that the non-hydrodynamical head region is confined at a narrow pancake surrounding the jet with a width ∼ 1/T and transverse radius ∼ 3/T . Outside this jet head region, the jet induced stress is well approximated by Navier-Stokes hydrodynamics. PACS numbers: 25.75.-q, 11.25.Tq, 13.87.-a

Jet Energy Loss and Mach Cones in pQCD vs . AdS / CFT
We compare away-side hadron correlations with respect to tagged heavy quark jets computed within a weakly coupled pQCD and a strongly coupled AdS/CFT model. While both models feature similar far zone Mach and diffusion wakes, the far zone stress features are shown to be too weak to survive thermal broadening at hadron freeze-out. Observable away-side conical correlations are dominated by the je...

متن کاملConical Di-jet Correlations from a Chromo-Viscous Neck in AdS/CFT
We show that Mach-like correlations from heavy quark jets in the Gubser et al AdS/CFT string drag model arise not from the expected (weak) hydrodynamical Mach sound wakes zone but from a near “Neck” zone where strong chromo-viscous field effects dominated and lead to a distinctive stress in the plasma of the form T Neck ∝ √ λT 2 0 Y (x)/x. We propose that measurement of the jet velocity depende...
متن کاملDi-jet conical correlations associated with heavy quark jets in anti-de sitter space/conformal field theory correspondence.
We show that far zone Mach and diffusion wake "holograms" produced by supersonic strings in anti-de Sitter space/conformal field theory (AdS/CFT) correspondence do not lead to observable conical angular correlations in the strict N_{c}-->infinity supergravity limit if Cooper-Frye hadronization is assumed. However, a special nonequilibrium "neck" zone near the jet is shown to produce an apparent...
متن کاملJet Nuclear Modification Factor from the AdS/CFT Correspondence
We define a novel definition of the holographic light hadron jet by a separation of scales from plasma to jet, which leads to the re-emergence of the late-time Bragg peak in the instantaneous jet energy loss rate. We use the holographic energy loss of light quark and our new jet prescription in AdS/CFT to calculate the nuclear modification factor of jet for a brick of plasma (both static and ex...
