Partonic effects on the elliptic flow at relativistic heavy ion collisions
(American Physical Society, 2002)
The elliptic flow in heavy ion collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. By converting the strings in the high energy density regions into partons, we find that the final ...
Giant monopole resonance strength in Si-28
(American Physical Society, 1998)
The giant resonance region in Si-28 was studied with inelastic scattering of 240 MeV alpha particles at small angles including 0 degrees. The giant resonance peak extended from E-x=12 MeV to 35 MeV and E0 strength corresponding ...
Pion interferometry in Au plus Au and Cu plus Cu collisions at s(NN)=62.4 and 200 GeV
(American Physical Society, 2009)
We present a systematic analysis of two-pion interferometry in Au+Au collisions at s(NN)=62.4 GeV and Cu+Cu collisions at s(NN)=62.4 and 200 GeV using the STAR detector at the Relativistic Heavy Ion Collider (RHIC). The ...
Deuteron-nucleus collisions in a multiphase transport model
(American Physical Society, 2003)
Using a multiphase transport model, we study pseudorapidity distributions and transverse momentum spectra in deuteron-gold collisions at RHIC. We find that final-state partonic and hadronic interactions affect the transverse ...
Subthreshold Antiproton Production in Nucleus-Nucleus Collisions
(American Physical Society, 1994)
Antiproton production in nucleus-nucleus collisions at energies below the threshold for its production from the nucleon-nucleon interaction in free space is studied in the relativistic Vlasov-Uehling-Uhlenbeck model. The ...
Nuclear modification factor of nonphotonic electrons in heavy-ion collisions, and the heavy-flavor baryon-to-meson ratio
(American Physical Society, 2009)
The nuclear modification factor R(AA) of nonphotonic electrons in Au + Au collisions at root(S)NN = 200 GeV is studied by considering the decays of heavy-flavor hadrons produced in a quark coalescence model. Although an ...
Isospin-dependent pion in-medium effects on the charged-pion ratio in heavy ion collisions
(American Physical Society, 2010)
Using results from the chiral perturbation theory for the s-wave interaction and the Delta-resonance model for the p-wave interaction of pions with nucleons, we evaluated the spectral functions of pions in asymmetric nuclear ...
Transport Model with Quasipions
(American Physical Society, 1993)
We extend the normal transport model to include the medium effect on pions by treating them as quasiparticles. The property of the quasipion is determined using the delta-hole model. Modelling heavy-ion collisions at ...
Kaon Production from Hot and Dense Matter Formed in Heavy-Ion Collisions
(American Physical Society, 1991)
In heavy-ion collisions, kaons can be produced from baryon-baryon, meson-baryon, and meson-meson interactions. Simple meson-exchange models are introduced to study kaon production from these processes in the free space. ...
Measurement of Spin-Correlation Parameters all and Asl in P-P Elastic-Scattering from 500 Mev to 800 Mev
(American Physical Society, 1992)
The spin-correlation observable A(LL) for p-p elastic scattering has been measured at energies 589, 640, 692, 743, and 793 MeV, over a c.m. angular range between 20-degrees and 100-degrees. The spin observable A(SL) was ...
