Strange quark collectivity of φ meson at RHIC
Based on AMPT model, the elliptic flow v2 of φ mesons which is reconstructed from KK at the Relativistic Heavy Ion Collider (RHIC) energy has been studied. The results show that reconstructed v2 of φmeson can keep the earlier information before φ decays and it seems to obey the number of constituent quark scaling as other mesons and baryons. This result indicates that the φ v2 mostly reflects t...
متن کاملElliptic flow of φmeson and strange quark collectivity at RHIC
Based on AMulti-Phase Transport model, the elliptic flow v2 of φmeson which is reconstructed from K+K− at top relativistic heavy ion collider (RHIC) energy at Brokehaven National Laboratory (BNL) has been studied. The dependences of the transverse momentum pT and of the centrality have been presented and the rescattering effect of φ in the hadronic phase has been also investigated. The results ...
متن کامل(Strange) Meson Interferometry at RHIC
We make predictions for the kaon interferometry measurements in Au+Au collisions at the Relativistic Heavy Ion Collider (RHIC). A first order phase transition from a thermalized Quark-Gluon-Plasma (QGP) to a gas of hadrons is assumed for the transport calculations. The fraction of kaons that are directly emitted from the phase boundary is considerably enhanced at large transverse momenta KT ∼ 1...
متن کاملφ- meson Production at RHIC energies using the PHENIX Detector
Light vector mesons are among the most informative probes to understand the strongly coupled Quark Gluon Plasma created at RHIC. The suppression of light mesons at high transverse momentum, compared to expectations from scaled p + p results, reflects the properties of the strongly interacting matter formed. The φ-meson is one of the probes whose systematic measurement in p + p, d + Au and Au + ...
متن کاملStrange Fluctuations at RHIC
Relativistic nuclear collisions can produce matter in which chiral symmetry is restored. One possible consequence of this restoration is the formation of disoriented chiral condensates (DCC) – transient regions in which the average chiral order parameter differs from its value in the surrounding vacuum. Previous efforts to describe DCC signals have focused on pion production. In Ref. [1], Gavin...
