Abstract
New measurements of rapidity-even dipolar flow, v, are presented for several transverse momenta, , and centrality intervals in Au+Au collisions at and GeV, U+U collisions at GeV, and Cu+Au, Cu+Cu, d+Au and p+Au collisions at ~GeV. The v shows characteristic dependencies on , centrality, collision system and , consistent with the expectation from a hydrodynamic-like expansion to the dipolar fluctuation in the initial state. These measurements could serve as constraints to distinguish between different initial-state models, and aid a more reliable extraction of the specific viscosity .
