Jet Nuclear Modification Factor from the AdS/CFT Correspondence
نویسنده
چکیده
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 expanding plasma) and compare the AdS/CFT results with the experimental data for most central Pb-Pb collision at LHC at 2.76 TeV center-of-mass energy. Defining a renormalized AdS/CFT jets that we argue better reflect QCD physics, we find a surprisingly good agreement between our toy model which is the first fully strongly coupled calculations, and preliminary jet suppression data from heavy ion collisions at LHC.

متن کاملJet Quenching Parameter in Medium with Chemical Potential from AdS/CFT
We calculate the jet quenching parameter in medium with chemical potential from AdS/CFT correspondence. Our result is summarized in a plot. Moreover, we extract the explicit form of the jet quenching parameter of medium with small chemical potential for phases of dual SYM corresponding to large and small black holes. For the former phase, the jet quenching is increased as the charge density inc...
متن کاملTesting AdS/CFT at LHC
After an introduction to jet phenomenology and tests of AdS/CFT at LHC we derive the heavy quark drag of a string dangling in a shock metric of AdS space, thus generalizing the AdS/CFT drag calculations in strongly coupled thermal media to momentum loss in both hot and cold nuclear matter.
متن کاملJet Quenching in Heavy Ion Collisions from AdS/CFT
The phenomenon of jet supression observed in highly energetic heavy ion collisions is discussed. The focus is devoted to the stunning applications of the AdS/CFT correspondence [1] to describe these real time processes, hard to be illuminated by other means. In particular, the introduction of as many flavors as colors into the quark-gluon plasma is scrutinized.
متن کاملDrag force in AdS/CFT
The AdS/CFT correspondence and a classical test string approximation are used to calculate the drag force on an external quark moving in a thermal plasma of N = 4 superYang-Mills theory. This computation is motivated by the phenomenon of jet-quenching in relativistic heavy ion collisions.
