Medium-induced gluon radiation in nucleus-nucleus collisions depends on both energy density and collective flow. This study disentangles these effects by analyzing particle production and jet correlations, revealing flow

Area of Science:

  • Nuclear physics
  • High-energy physics
  • Quantum chromodynamics

Background:

  • High-energy partons interact with a dense medium in nucleus-nucleus collisions.
  • This medium exhibits significant collective flow, influencing parton interactions.

Purpose of the Study:

  • To demonstrate that medium-induced gluon radiation depends on both energy density and collective flow.
  • To disentangle the contributions of energy density and collective flow to gluon radiation.

Main Methods:

  • Measurement of particle production associated with high-transverse momentum (pT) trigger particles.
  • Analysis of jetlike correlations and jets.
  • Examination of the eta x phi distribution of average jet energy and multiplicity.

Main Results:

  • Medium-induced gluon radiation is influenced by collective flow, not just energy density.
  • Flow effects cause a characteristic breaking of rotational symmetry in jet properties.
  • Data from Au + Au collisions suggest longitudinal collective flow distorts parton fragmentation.

Conclusions:

  • Collective flow is a crucial factor in understanding medium-induced gluon radiation.
  • Rotational symmetry breaking in jet distributions serves as a signature of flow effects.
  • Further analysis of jet correlations can provide evidence for flow-induced parton fragmentation distortion.
