Measurement of Harmonic Flow from Heavy Ion Collisions in ATLAS
The ATLAS Collaboration has measured the flow of charged particles as the medium formed in (Pb-Pb) collisions at the LHC expands after the interaction.

| Sumario: | The ATLAS Collaboration has measured the flow of charged particles as the medium formed in (Pb-Pb) collisions at the LHC expands after the interaction. The Fourier expansion of distributions of two particle correlations in azimuth angle is consistent with an acoustic harmonic expansion of a system with very low viscosity. The power spectrum of such a flow is shown up to 15th order. |
