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 ...
Pion femtoscopy in p plus p collisions at root s=200 GeV
(American Physical Society, 2011)
The STAR Collaboration at the BNL Relativistic Heavy Ion Collider has measured two-pion correlation functions from p + p collisions at root s = 200 GeV. Spatial scales are extracted via a femtoscopic analysis of the ...
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 ...
Medium modifications of the rho meson in nuclear photoproduction
(American Physical Society, 2010)
We extend our recent study of dilepton invariant-mass spectra from the decays of rho mesons produced by photon reactions off nuclei. We specifically focus on experimental spectra as recently measured by the CLAS Collaboration ...
Structure of (23)Al from the one-proton breakup reaction and astrophysical implications
(American Physical Society, 2011)
The ground state of the proton-rich nucleus (23)Al has been studied by one-proton removal on a carbon target at about 50 MeV/nucleon using the EXOGAM + SPEG experimental setup at GANIL. Longitudinal momentum distributions ...
Cooperative recombination of electron-hole pairs in semiconductor quantum wells under quantizing magnetic fields
(American Physical Society, 2010)
We present results of detailed investigations of light emission from semiconductor multiple quantum wells at low temperatures and high magnetic fields excited by intense femtosecond laser pulses. The intensity and linewidth ...
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, ...
