Femtosecond-scale response of GaAs to ultrafast laser pulses RID A-7793-2008
(American Physical Society, 2002)
We present nonadiabatic simulations of the coherent response of crystalline GaAs irradiated by intense femtosecond-scale laser pulses. Above a threshold fluence, which corresponds to promotion of about 12% of the valence ...
Delta phi Delta eta correlations in central Au plus Au collisions at root S-NN = 200 GeV
(American Physical Society, 2007)
We report charged particle pair correlation analyses in the space of Delta phi (azimuth) and Delta eta (pseudorapidity), for central Au+Au collisions at root s(NN)=200 GeV in the STAR detector. The analysis involves ...
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 ...
Ratios of heavy baryons to heavy mesons in relativistic nucleus-nucleus collisions
(American Physical Society, 2009)
Heavy baryon/meson ratios Lambda(c)/D(0) and Lambda(b)/(B) over bar (0) in relativistic heavy ion collisions are studied in the quark coalescence model. For heavy baryons, we include production from coalescence of heavy ...
Determination of the direct capture contribution for N-13(p,gamma)O-14 from the O-14 -> N-13+p asymptotic normalization coefficient
(American Physical Society, 2004)
N-13(p, gamma)O-14 is one of the key reactions which trigger the onset of the hot CNO cycle. This transition occurs when the proton capture rate on 13N is faster, due to increasing stellar temperature (greater than or equal ...
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 ...
Giant resonances in (116)Sn from 240 MeV (6)Li scattering
(American Physical Society, 2009)
Giant resonances in (116)Sn were measured by inelastic scattering of (6)Li ions at E(6)Li=240 MeV over the angle range 0(degrees)-6(degrees). Isoscalar E0-E3 strength distributions were obtained with a double folding model ...
Quantum theory of a micromaser operating on the atomic scattering from a resonant standing wave
(American Physical Society, 2001)
We study the amplification of a resonant standing-wave light field due to the interaction with a beam of monovelocity two-level atoms moving in the Raman-Nath regime and in the Bragg regime. The atomic density is low so ...
