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 ...
First observation of alpha-cluster states in the (14)O+(4)He interaction
(American Physical Society, 2008)
We measured (14)O+(4)He excitation functions for elastic scattering which demonstrate, for the first time, a well developed alpha-cluster structure in the proton rich nucleus, (18)Ne. We present the excitation energies and ...
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 ...
Model for J/psi absorption in hadronic matter
(American Physical Society, 2000)
The cross sections for J/psi absorption by pi and rho mesons are studied in a meson-exchange model that includes not only pseudoscalar-pseudoscalar-vector-meson couplings but also three-vector-meson and four-point couplings. ...
Cross sections for pentaquark baryon production from protons in reactions induced by hadrons and photons
(American Physical Society, 2003)
Using hadronic Lagrangians that include the interaction of pentaquark Theta(+) baryon with K and N, we evaluate the cross sections for its production from meson-proton, proton-proton, and photon-proton reactions near ...
Azimuthal anisotropy in Au plus Au collisions at root S-NN=200 GeV
(American Physical Society, 2005)
The results from the STAR Collaboration on directed flow (v(1)), elliptic flow (v(2)), and the fourth harmonic (v(4)) in the anisotropic azimuthal distribution of particles from Au+Au collisions at root s(NN) = 200 GeV are ...
Superallowed 0(+)-> 0(+) nuclear beta decays: A critical survey with tests of the conserved vector current hypothesis and the standard model
(American Physical Society, 2005)
A complete and critical survey is presented of all half-life, decay-energy, and branching-ratio measurements related to 20 superallowed 0(+)-> 0(+) decays
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 ...
Character of states near the Fermi level in (Ga,Mn)As: Impurity to valence band crossover RID E-6453-2010
(American Physical Society, 2007)
We discuss the character of states near the Fermi level in Mn-doped GaAs, as revealed by a survey of dc transport and optical studies over a wide range of Mn concentrations. A thermally activated valence-band contribution ...
Correlations in noisy Landau-Zener transitions
(American Physical Society, 2004)
We analyze the influence of colored classical Gaussian noise on Landau-Zener transitions during a two-level crossing in a time-dependent regular external field. Transition probabilities and coherence factors become random ...
