DISAPPEARANCE OF ROTATIONAL FLOW AND REACTION PLANE DISPERSIONS IN Kr+Au COLLISIONS
نویسندگان
چکیده
Recently, a new method has been proposed to extract single particle triple differential azimuthal distributions from two particles azimuthal correlation functions. In this article, we report the applications of this method to the Kr + Au reactions. Measurements with Kr ions at beam energies of E/A = 35, 55, and 70 MeV were performed with beams from the K1200 cyclotron of the National Superconducting Cyclotron Laboratory of Michigan State University (NSCL/MSU). Measurements at E/A = 100 MeV were performed at the Laboratoire National SATURNE at Saclay. The emitted charged particles were detected with the combined MSU Miniball/Washington University Miniwall 4π phoswich detector array. Unit charge resolution up to Z = 10 was routinely achieved for particles that transversed the fast plastic scintillator. To avoid the complexities in determining the reaction planes, two particle correlations have been used to extract the energy where sideward or rotational flow disappears [1]. The azimuthal correlation function is defined as

Disappearance of Transverse Flow in Central Collisions for Heavier Nuclei
Using the Quantum Molecular Dynamics model, we analyze the disappearance of flow in heavier colliding nuclei. A power law mass dependence (∝ 1 √ A ) is obtained in all cases. Our results are in excellent agreement with experimental data which allows us to predict the balance energy for U + U collision around 37-39 MeV/nucleon. Thirty years ago it was predicted by Scheid and Greiner [1] that in ...

متن کاملTransition from in-plane to out-of-plane azimuthal enhancement in Au+Au collisions
The incident energy at which the azimuthal distributions in semi-central heavy ion collisions change from in-plane to out-of-plane enhancement – Etran is studied as a function of mass of emitted particles, their transverse momentum and centrality for Au+Au collisions. The analysis is performed in a reference frame rotated with the sidewards flow angle (Θflow) relative to the beam axis. A system...
متن کاملWays to constrain the away side jet in Au + Au collisions in PHENIX
We discussed methods used by the PHENIX to constrain the flow background in the two particle jet correlation. Both the background level and elliptic flow can be reliably decomposed from the jet contribution. We also studied the non-flow contribution to the reaction plane elliptic flow due to dijets. We found the jet bias is negligible in PHENIX, when the reaction plane is measured at Beam Beam ...
متن کاملPredictions of Elliptic flow and nuclear modification factor from 200 GeV U + U collisions at RHIC Hiroshi
Predictions of elliptic flow (v2) and nuclear modification factor (RAA) are provided as a function of centrality in U + U collisions at √ s NN = 200 GeV. Since the U nucleus is naturally deformed, one could adjust the properties of the fireball, density and duration of the hot and dense system, for example, in high energy nuclear collisions by carefully selecting the colliding geometry. Within ...
