摘要：

Independent experimental constraints on the initial condition assumed in hydrodynamics to predict collective flow in Au+Au at 200 AGeV are essential to strengthen the case for the "perfect fluid" property of deconfined quark-gluon matter. We propose a 3D jet tomographic test of possible novel initial surface geometries predicted by a color glass condensate model of initial conditions. We show that high p(T) and rapidity, eta, differential directed flow v(1)(p(T)> 6,\eta\> 1) is sensitive to the generic rapidity twist of the bulk low p(T) matter in the reaction plane and can differentiate between conventional diffuse Glauber surfaces and sharper surfaces possible in some parametrizations of the color glass condensate.
