Directed flow at midrapidity in sqrt(s_NN)=2.76 TeV Pb+Pb collisions
read the original abstract
We analyze published data from the ALICE Collaboration in order to obtain the first extraction of the recently-proposed rapidity-even directed flow observable v1. An accounting of the correlation due to the conservation of transverse momentum restores the factorization seen by ALICE in all other Fourier harmonics and thus indicates that the remaining correlation gives a reliable measurement of directed flow. We then carry out the first viscous hydrodynamic calculation of directed flow, and show that it is less sensitive to viscosity than higher harmonics. This allows for a direct extraction of the dipole asymmetry of the initial state, providing a strict constraint on the non-equilibrium dynamics of the early-time system. A prediction is then made for v1 in Au-Au collisions at RHIC.

Rapidity-even Dipolar Flow in Relativistic Heavy-Ion Collisions
GMC-suppressed rapidity-even dipolar flow correlations in AMPT and HIJING at 200 GeV show sensitivity to partonic transport and initial-state eccentricity correlations.
