Flow harmonics vₙ at finite density

الأصل · EN

We generalize the Gubser solution of viscous hydrodynamics by including the finite density effect and analytically compute the flow harmonics vₙ. We explicitly show how vₙ and their viscous corrections depend on the chemical potential. The difference in vₙ between particles and antiparticles is also analytically computed and shown to be proportional to various chemical potentials and the viscosity. Excellent agreement is obtained between the results and the available experimental data from the SPS, RHIC and the LHC.
