Abstract

γ production in heavy ion collisions at RHIC energy is investigated. While the transverse momentum spectra of the ground state γ(1s) are controlled by the initial state Cronin effect, the excited bb⁻ states are characterized by the competition between the cold and hot nuclear matter effects and sensitive to the dissociation temperatures determined by the heavy quark potential. We emphasize that it is necessary to measure the excited heavy quark states in order to extract the early stage information in high energy nuclear collisions at RHIC.

Anisotropic flow nu2 in Au + Au collisions at RHIC

Journal Article Lu, Y ; Bleicher, M ; Liu, F ; ... - Journal of Physics G

Using the RQMD model, transverse momentum dependence of the anisotropic flow v{sub 2} for {pi}, K, nucleon, {phi}, and {lambda}, are studied for Au + Au collisions at {radical}s{sub NN} = 200 GeV. Both hydrodynamic hadron-mass hiragracy (hhmh) at low p{sub T} region and particle type dependence (baryon versus meson) at the intermediate p{sub T} region are reproduced with the model calculations although the model underpredicted the overall values of v{sub 2} by a factor of 2-3. As expected, when the rescatterings are turned off, all v{sub 2} becomes zero. The failure of the hadronic model in predicting the absolutemore »« less

High Transverse Momentum {eta} Meson Production in p+p,d+Au and Au+Au Collisions at sqrt(s_NN) = 200 GeV

Journal Article Adler, S. S. ; Awes, Terry C ; Batsouli, Sotiria ; ... - Physical Review C

Inclusive transverse momentum spectra of {eta} mesons in the range p{sub T}{approx}2-12 GeV/c have been measured at midrapidity (|{eta}|<0.35) by the PHENIX experiment at RHIC in p+p,d+Au, and Au+Au collisions at {radical}R{sub NN}=200 GeV. The eta mesons are reconstructed through their {eta}{yields}{gamma} {gamma} channel for the three colliding systems as well as through the {eta}{yields}{pi}{sup 0}{pi}{sup +}{pi}{sup -} decay mode in p+p and d+Au collisions. The nuclear modification factor in d+Au collisions, RdAu(p{sub T}){approx}1.0-1.1, suggests at most only modest pT broadening ('Cronin enhancement'). In central Au+Au reactions, the eta yields are significantly suppressed, with RAuAu(p{sub T}){approx}0.2. The ratio of {eta}more »« less

Probing triaxial deformation of atomic nuclei in high-energy heavy ion collisions

Journal Article Jia, Jiangyong - Physical Review. C

Most atomic nuclei are deformed with a quadrupole shape described by its overall strength β₂ and triaxiality γ. The deformation can be accessed in high-energy heavy ion collisions by measuring the collective flow response of the produced quark-gluon plasma to the eccentricity ε₂ and the density gradient d_⊥ in the initial state. Using an analytical estimate and a Glauber model, I show that the variancesmore »« less

Matter in extremis: Ultrarelativistic nuclear collisions at RHIC

Journal Article Jacobs, Peter ; Wang, Xin-Nian - Progress in Particle and Nuclear Physics

We review the physics of nuclear matter at high energy density and the experimental search for the Quark-Gluon Plasma at the Relativistic Heavy Ion Collider (RHIC). The data obtained in the first three years of the RHIC physics program provide several lines of evidence that a novel state of matter has been created in the most violent, head-on collisions of Au nuclei at {radical}s = 200 GeV. Jet quenching and global measurements show that the initial energy density of the strongly interacting medium generated in the collision is about two orders of magnitude larger than that of cold nuclear matter,more »« less
