Soft-collinear effective theory for hadronic and nuclear collisions: The evolution of jet quenching from RHIC to the highest LHC energies
نویسنده
چکیده
In the framework of soft-collinear effective theory with Glauber gluons, results and predictions for inclusive hadron suppression, based upon in-medium parton shower evolution, are presented for Au+Au and Pb+Pb collisions at RHIC and LHC energies √ s = 200 AGeV and √ s = 2.76, 5.1 ATeV, respectively. The SCETG medium-induced splitting kernels are further implemented to evaluate the attenuation of reconstructed jet cross in such reactions and to examine their centrality and radius R dependence. Building upon a previously developed method to systematically resum the jet shape at next-to-leading logarithmic accuracy, a quantitative understanding of the jet shape modification measurement in Pb+Pb collisions at √ s = 2.76 ATeV at the LHC can be achieved. Predictions for photon-tagged jet cross sections and shapes, that can shed light on the parton flavor dependence of in-medium parton shower modification, are also given.

Jet quenching phenomenology from soft-collinear effective theory with Glauber gluons.
We present the first application of a recently developed effective theory of jet propagation in matter, soft-collinear effective theory with Glauber gluons (SCET_{G}), to inclusive hadron suppression in nucleus-nucleus collisions at RHIC and the LHC. SCET_{G}-based splitting kernels allow us to go beyond the traditional energy loss approximation and unify the treatment of vacuum and medium-indu...

In these lectures I introduce aspects of current theory used to interpret the preliminary data on ultra-relativistic nuclear collisions at RHIC energies in terms of the physical properties of QCD matter at extreme densities. Topics covered include: What are the physics questions at SPS and RHIC?, Geometrical vs Dynamical features of A+A, the interplay of computable Hard pQCD vs phenomenological...
متن کاملSimulation of Jet Quenching in Heavy Ion Collisions
One of the important tools for studying the properties of quark-gluon plasma (QGP) in ultrarelativistic heavy ion collisions is the analysis of a QCD jet production. The medium-induced energy loss of energetic partons, “jet quenching”, should be very different in the cold nuclear matter and QGP, resulting in many observable phenomena . Recent RHIC data on high-pT particle production at √ s = 20...
متن کاملSoft-hadronic Observables for Relativistic Heavy-ion Collisions at Rhic and Lhc * * *
The relativistic hydrodynamics together with the single-freeze-out statistical hadronization model is used to describe the midrapidity hadron production in ultra-relativistic heavy-ion collisions at RHIC and LHC. At the highest RHIC energy our approach gives a quite satisfactory global description of soft hadronic observables including the HBT radii. With the increased initial energy, from RHIC...
متن کاملA Parton-Hadron Cascade Approach in High-energy Nuclear Collisions
Event generators based on perturbative QCD (pQCD) are proposed such as HIJING (Heavy Ion Jet Interaction Generator)[1], VNI (Vincent Le Cucurullo Con Giginello)[2], in order to describe ultra-relativistic heavy ion collisions, especially, at collider energies (RHIC/LHC). Although both models reproduce many pp and p̄p data, there are large discrepancies in AA collisions between these two models, ...
