Jet-quenching and momentum correlators from the gauge-string duality
نویسندگان
چکیده
I relate the jet-quenching parameter, defined as q̂ = p⊥/λ, for an external quark moving through a thermal plasma of N = 4 gauge theory, to a two-point function of transverse displacements of the quark’s worldline. This two-point function can be computed using the gauge-string duality. I comment on the possible relevance of the string theory calculation to heavy quarks propagating through a quark-gluon plasma.

Free Field Theory as a String Theory?
An approach to systematically implement open-closed string duality for free large N gauge theories is summarised. We show how the relevant closed string moduli space emerges from a reorganisation of the Feynman diagrams contributing to free field correlators. We also indicate why the resulting integrand on moduli space has the right features to be that of a string theory on AdS.
متن کاملDEVELOPMENT IN STRING THEORY
The string theory is a fast moving subject, both physics wise and in the respect of mathematics. In order to keep up with the discipline it is important to move with new ideas which are being stressed. Here I wish to give extracts from new papers of ideas which I have recently found interesting. There are six papers which are involved: I ."Strings formulated directly in 4 dimensions " A. N...
متن کاملOn jet quenching parameters in strongly coupled non-conformal gauge theories
Recently Liu, Rajagopal and Wiedemann (LRW) [1] proposed a first principle, nonperturbative quantum field theoretic definition of “jet quenching parameter” q̂ used in models of medium-induced radiative parton energy loss in nucleus-nucleus collisions at RHIC. Relating q̂ to a short-distance behavior of a certain light-like Wilson loop, they used gauge theory-string theory correspondence to evalua...
متن کاملString Representation of Field Correlators in the Dual Abelian Higgs Model
By making use of the path integral duality transformation, we derive the string representation for the partition function of an extended Dual Abelian Higgs Model containing gauge fields of external currents of electrically charged particles. By the same method, we obtain the corresponding representations for the generating functionals of gauge field and monopole current correlators. In the case...
متن کاملMomentum fluctuations of heavy quarks in the gauge-string duality
Using the gauge-string duality, I compute two-point functions of the force acting on an external quark moving through a finite temperature bath of N = 4 super-Yang-Mills theory. I comment on the possible relevance of the string theory calculations to heavy quarks propagating through a quark-gluon plasma.
