Quarkonium Production in PHENIX [PDF]

, 2007
Quarkonia provide a sensitive probe of the properties of the hot dense medium created in high energy heavy ion collisions. Hard scattering processes result in the production of heavy quark pairs that interact with the collision medium during ...

Effects of configuration mixing in heavy-ion elastic scattering

EPJ Web of Conferences, 2014
A theoretical study of the influence of configuration mixing on elastic scattering cross section is performed for the system 16O + 27Al at 100 MeV. A simple twostate model space, including the 27Al 5/2+ ground and 5/2+ excited state at 2.73 MeV, is used ...

The QCD Pomeron in Ultraperipheral Heavy Ion Collisions: V. Double Vector Meson Production in the BFKL Approach [PDF]

, 2005
In this work the double vector meson production in ultraperipheral heavy ion collisions is investigated within the BFKL approach. The integrated cross sections and event rates for the processes AA --> V1 V2 AA (V_i = rho, omega, phi, J/Psi, Upsilon) are ...

Probing surface diffuseness of nucleus-nucleus potential with quasielastic scattering at deep sub-barrier energies [PDF]

, 2005
We perform a systematic study on the surface property of nucleus-nucleus potential in heavy-ion reactions using large-angle quasielastic scattering at energies well below the Coulomb barrier.

Lambda-Lambda Correlation in Relativistic Heavy Ion Collisions

EPJ Web of Conferences, 2015
We investigate Λ − Λ correlation function in relativistic heavy ion collisions to extract their interaction. Using an expanding source model for heavy ion collisions, we disentangle effects of collective expansion and those of the interaction at low ...

Monte Carlo Models: Quo Vadimus? [PDF]

, 2001
Coherence, multiple scattering and the interplay between soft and hard processes are discussed. These physics phenomena are essential for understanding the nuclear dependences of rapidity density and $p_T$ spectra in high-energy heavy-ion collisions. The
