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 ...
Effects of geometry and impurities on quantum rings in magnetic fields RID D-3014-2009
(American Physical Society, 2006)
We investigate the effects of impurities and changing ring geometry on the energetics of quantum rings under different magnetic field strengths. We show that as the magnetic field and/or the electron number are/is increased, ...
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 ...
Semiclassical framework for the calculation of transport anisotropies
(American Physical Society, 2009)
We present a procedure for finding the exact solution to the linear-response Boltzmann equation for two-dimensional anisotropic systems and demonstrate it on examples of noncrystalline anisotropic magnetoresistance in a ...
Short-time-evolved wave functions for solving quantum many-body problems
(American Physical Society, 2003)
The exact ground state of a strongly interacting quantum many-body system can be obtained by evolving a trial state with finite overlap with the ground state to infinite imaginary time. In many cases, since the convergence ...
