Thermalization of heavy quarks in the quark-gluon plasma
(American Physical Society, 2005)
Charm- and bottom-quark rescattering in a quark-gluon plasma (QGP) is investigated with the objective of assessing the approach toward thermalization. Employing a Fokker-Planck equation to approximate the collision integral ...
The N-14(Be-7,B-8)C-13 reaction and the Be-7(p,gamma)B-8 S factor
(American Physical Society, 1999)
The N-14(Be-7,B-8)C-13 reaction was studied using an 85 MeV Be-7 radioactive beam. The asymptotic normalization coefficients for the virtual transitions Be-7+pB-8 were determined from the measured cross section. These ...
Multiplicity and pseudorapidity distributions of charged particles and photons at forward pseudorapidity in Au plus Au collisons at root s(NN)=62.4 GeV
(American Physical Society, 2006)
We present the centrality-dependent measurement of multiplicity and pseudorapidity distributions of charged particles and photons in Au+Au collisions at root s(NN)=62.4 GeV. The charged particles and photons are measured ...
Cross section for charmonium absorption by nucleons
(American Physical Society, 2002)
The cross section for J/psi absorption by nucleons is studied using a gauged SU(4) hadronic Lagrangian but with empirical particle masses, which has been used previously to study the cross sections for J/psi absorption by ...
Asymptotic normalization coefficients and the Be-7(p, gamma)B-8 astrophysical S factor
(American Physical Society, 2001)
We consider the results of two proton transfer reactions, B-10(Be-7, B-8)Be-9 and N-14(Be-7, B-8)C-13, to obtain a weighted average of the measured asymptotic normalization coefficients for the virtual transition 7Be +pB-8. ...
J/Psi suppression in ultrarelativistic nuclear collisions
(American Physical Society, 2000)
Using a multiphase transport model, we study the relative importance of J/psi suppression mechanisms due to plasma screening, gluon scattering, and hadron absorption in heavy ion collisions at the Relativistic Heavy Ion ...
Charm elliptic flow in relativistic heavy-ion collisions RID A-2398-2009
(American Physical Society, 2005)
Charm elliptic flow in heavy-ion collisions at the Relativistic Heavy Ion Collider is studied in a multiphase transport model. Assuming that the cross section for charm quark scattering with other light quarks is the same ...
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 ...
Antiferromagnetic domain size and exchange bias
(American Physical Society, 2008)
Using neutron diffraction, we measured the sizes of antiferromagnetic domains in three ferromagnet/antiferromagnet bilayer samples as a function of the magnitude and sign of exchange bias, temperature, and antiferromagnet ...
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. ...
