What can we learn from dijets? A systematic study at RHIC with VNI/BMS

Published

Journal Article

We present a systematic study of dijet suppression at RHIC using the VNI/BMS parton cascade. We examine the medium modification of the dijet asymmetry A j and the energy distribution within the dijets (jet-shape). Understanding the sensitivity of these observables to properties of the deconfined medium and to experimental factors is vital if dijets are to be useful for QCD tomography. VNI/BMS provides a controllable test-bed with sufficient complexity to model jet modification without confounding results with fluctuations from hydrodynamics and hadronization. Dijets are examined under the modification of: the jet transport coefficient qhat; the path length of leading and sub-leading jets; jet cone angle and the jet-medium interaction mechanism. We find that A j is very sensitive to the distance traveled by the secondary jet, the jet shape is dominated by qhat and the nature of the interaction mechanism. © 2012 Elsevier B.V.
