Beam Energy Dependence of First and Higher-Order Flow Harmonics from the STAR Experiment at RHIC

In these proceedings, we present STAR measurements of directed flow, v1, for pions, protons and antiprotons between sNN=7.7 GeVand200GeV. A striking observation is that the v1 slope for net protons as a function of normalized rapidity y′(y/ybeam),F=dv1/dy′, which is an estimate of the directed flow contribution from baryon number transported to the midrapidity region, changes sign twice within the lower part of this energy range. We also present the measured beam energy dependence of triangular flow v3, and the n=1 to n=5 flow harmonics for charged particles at 200 GeV.
