Rapidity and system size dependence of anisotropic flows in relativistic heavy ion collisions
The azimuthal anisotropy of hadron transverse momentum distributions in heavy ion collisions at RHIC is sensitive to the properties of produced matter. In the framework of transport approach, it was shown in Ref.[ 1] using the ZPC model [ 2] that the value of the second harmonic, i.e., the elliptic flow, depends sensitively on the magnitude of parton scattering cross sections. With a more reali...
متن کاملSystem Size Dependence of Azimuthal Correlations in Relativistic Heavy Ion Collisions
Systematic comparisons of jet pair correlations obtained in Cu+Cu and Au+Au collisions at √ sNN =200 GeV are presented. The measured jet-pair distributions for both systems show strong modification of the away-side jet. For the same number of participating nucleons, the modification does not show a strong dependence on the collision system. It is suggested that such comparisons can provide impo...
متن کاملElliptic flow of deuterons in relativistic heavy-ion collisions
Using a dynamical model based on the NN → dπ,NNN → dN , and NNπ → dπ reactions and measured proton and pion transverse momentum spectra and elliptic flows, we study the production of deuterons and their elliptic flow in heavy-ion collisions at RHIC. The results are compared with those from the coalescence model. The deviation of deuteron elliptic flow from the constituent nucleon number scaling...
متن کاملdependence of transverse flow in relativistic heavy - ion collisions
The strength of transverse flow is examined as a function of transverse momentum p t using a simple, transversely moving thermal model and a more realistic, relativistic transport model (ART). It is shown that the p t dependence reveals useful information about the collective flow that is complementary to that obtained from the standard in-plane transverse momentum analysis. Interesting feature...
متن کاملHubble-like flows in relativistic heavy-ion collisions
We study the dynamical appearance of scaling solutions in relativistic hydrodynamics. The phase transition effects are included through the temperature dependent sound velocity. If a pre-equilibrium transverse flow is included in the initial conditions, then it may reach the form of the asymptotic Hubble flow, r/t, in short evolution times, 7-15 fm. The numerical solutions are found to support ...
