Charged particle rapidity distributions at relativistic energies
(American Physical Society, 2001)
Using a multiphase transport model (AMPT), which includes both initial partonic and final hadronic interactions, we study the rapidity distributions of charged particles such as protons, antiprotons, pions, and kaons in ...
Low-temperature magnetization of (Ga,Mn) As semiconductors
(American Physical Society, 2006)
We report on a comprehensive study of the ferromagnetic moment per Mn atom in (Ga,Mn)As ferromagnetic semiconductors. Theoretical discussion is based on microscopic calculations and on an effective model of Mn local moments ...
Landau-Zener transitions in a linear chain
(American Physical Society, 2002)
We present an exact asymptotic solution for electron transition amplitudes in an infinite linear chain driven by an external time-dependent electric field. This solution extends the Landau-Zener theory for the case of an ...
Hadronic scattering of charmed mesons
(American Physical Society, 2000)
The scattering cross sections of charm mesons with hadrons such as the pion, rho meson, and nucleon are studied in an effective Lagrangian. In heavy ion collisions, rescattering of produced charm mesons by hadrons affects ...
Transverse-momentum dependent modification of dynamic texture in central Au+Au collisions at root s(NN)=200 GeV RID B-7517-2009
(American Physical Society, 2005)
Correlations in the hadron distributions produced in relativistic Au+Au collisions are studied in the discrete wavelet expansion method. The analysis is performed in the space of pseudorapidity (vertical bar eta vertical ...
K-*(892)(0) production in relativistic heavy ion collisions at root s(NN)=130 GeV
(American Physical Society, 2002)
We report the first observation of K-*(892)(0)-->piK in relativistic heavy ion collisions. The transverse momentum spectrum of (K-*0+(K) over bar (*0))/2 from central Au+Au collisions at roots(NN)=130 GeV is presented. The ...
D-sJ(2317) meson production in ultrarelativistic heavy ion collisions RID A-2398-2009
(American Physical Society, 2007)
Production of D-sJ(2317) mesons in relativistic heavy ion collisions at the BNL Relativistic Heavy Ion Collider is studied. Using the quark coalescence model, we first determine the initial number of D-sJ(2317) mesons ...
Forward Lambda production and nuclear stopping power in d+Au collisions at root s(NN)=200 GeV
(American Physical Society, 2007)
We report the measurement of Lambda and (Lambda) over bar yields and inverse slope parameters in d+Au collisions at root s(NN)=200 GeV at forward and backward rapidities (y=+/- 2.75), using data from the STAR forward time ...
High-energy behavior of the nuclear symmetry potential in asymmetric nuclear matter RID A-2398-2009
(American Physical Society, 2005)
Using the relativistic impulse approximation with empirical NN scattering amplitude and the nuclear scalar and vector densities from the relativistic mean-field theory, we evaluate the Dirac optical potential for neutrons ...
