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 ...
Fast quantum noise in the Landau-Zener transition
(American Physical Society, 2007)
We show by direct calculation starting from a microscopic model that the two-state system with time-dependent energy levels in the presence of fast quantum noise obeys the master equation. The solution of master equation ...
Creation and pinning of vortex-antivortex pairs
(American Physical Society, 2006)
Computer modeling is reported about the creation and pinning of a magnetic vortex-antivortex (V-AV) pair in a superconducting thin film, due to the magnetic field of a vertical magnetic dipole above the film, and two antidot ...
Determination of the astrophysical S factor for C-11(p,gamma)N-12 from the N-12 -> C-11+p asymptotic normalization coefficient
(American Physical Society, 2003)
The evolution of very low-metallicity, massive stars depends critically on the amount of CNO nuclei that they produce. Alternative paths from the slow 3alpha process to produce CNO seed nuclei could change their fate. The ...
Partonic coalescence in relativistic heavy ion collisions
(American Physical Society, 2003)
Using a covariant coalescence model, we study hadron production in relativistic heavy ion collisions from both soft partons in the quark-gluon plasma and hard partons in minijets. Including transverse flow of soft partons ...
Search for temperature and N/Z dependent effects in the decay of A=98 compound nuclei
(American Physical Society, 2004)
Fusion-evaporation reactions induced by 110 MeV B-11 and radioactive C-11 on Rb-87 targets have been studied by measuring evaporation residue-light particle coincidences. The proton to alpha particle ratio in each reaction ...
