Precise half-life measurement of the superallowed beta(+) emitter (10)C
(American Physical Society, 2008)
The half-life of (10)C has been measured to be 19.310(4) s, a result with 0.02% precision, which is a factor of three improvement over the best previous result. Since (10)C is the lightest superallowed 0(+)-> 0(+) beta(+) ...
One-atom correlated-emission laser RID C-6638-2008
(American Physical Society, 2008)
We study a four-level double-Lambda atomic configuration working as a two photon linear amplifier where two atomic transitions independently interact with cavity mode, while the other transitions are driven by a strong ...
Nucleon and Delta resonances in K Sigma(1385) photoproduction from nucleons
(American Physical Society, 2008)
The reaction mechanisms for K Sigma(1385) photoproduction from the reaction gamma p -> K(+)Sigma(0)(1385) in the resonance energy region are investigated in a hadronic model. Both contributions from N and Delta resonances ...
Hadronic resonance production in d+Au collisions at root S(NN) = 200 GeV measured at the BNL Relativistic Heavy Ion Collider
(American Physical Society, 2008)
We present the first measurements of the rho(770)(0),K(*)(892),Delta(1232)(++),Sigma(1385), and Lambda(1520) resonances in d+Au collisions at s(NN)=200 GeV, reconstructed via their hadronic decay channels using the STAR ...
Centrality dependence of charged hadron and strange hadron elliptic flow from root s(NN)=200 GeVAu+Au collisions
(American Physical Society, 2008)
We present STAR results on the elliptic flow upsilon(2) Of charged hadrons, strange and multistrange particles from,root s(NN) = 200 GeV Au+Au collisions at the BNL Relativistic Heavy Ion Collider (RHIC). The detailed study ...
Probing nuclear matter with jet conversions
(American Physical Society, 2008)
We discuss the flavor of leading jet partons as a valuable probe of nuclear matter. We point out that the coupling of jets to nuclear matter naturally leads to an alteration of jet chemistry even at high transverse momentum ...
Heavy quark production from jet conversions in a quark-gluon plasma
(American Physical Society, 2008)
Recently, it has been demonstrated that the chemical composition of jets in heavy ion collisions is significantly altered compared to the jets in the vacuum. This signal can be used to probe the medium formed in nuclear ...
Enhanced strange baryon production in Au+Au collisions compared to p+p at root s(NN)=200 GeV
(American Physical Society, 2008)
We report on the observed differences in production rates of strange and multistrange baryons in Au+Au collisions at s(NN)=200 GeV compared to p+p interactions at the same energy. The strange baryon yields in Au+Au collisions, ...
Pion production by protons on a thin berylLium target at 6.4, 12.3, and 17.5 GeV/c incident proton momenta
(American Physical Society, 2008)
An analysis of inclusive pion production in proton-berylLium collisions at 6.4, 12.3, and 17.5 GeV/c proton beam momentum has been performed. The data were taken by Experiment 910 at the Alternating Gradient Synchrotron ...
Photon bremsstrahlung and diffusive broadening of a hard jet
(American Physical Society, 2008)
The photon bremsstrahlung rate from a quark jet produced in deep-inelastic scattering (DIS) off a large nucleus is studied in the collinear limit. The leading medium-enhanced higher twist corrections that describe the ...
