Hadron production from quark coalescence and jet fragmentation
(American Physical Society, 2005)
Transverse momentum spectra of pions, protons, and antiprotons in Au+Au collisions at intermediate RHIC energy root s(NN)=62 GeV are studied in a model that includes both quark coalescence from the dense partonic matter ...
Specific-heat discontinuity in impure two-band superconductors
(American Physical Society, 2003)
The Ginzburg-Landau coefficients and the jump of the specific heat are calculated for a disordered two-band superconductor. We start with the analysis of a more general case with arbitrary anisotropy. While the specific-heat ...
Isoscalar electric multipole strength in C-12
(American Physical Society, 2003)
The excitation region in C-12 below E-x=45 MeV was studied using 240 MeV alpha-particle scattering. Elastic scattering was measured from theta(c.m.)=3.8degrees to 49.4degrees and density dependant folding optical model ...
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 ...
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 ...
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 ...
