Accurate measurement of F-2(d)/F-2(p) and R(d)-R(p)
Arneodo M, Arvidson A, Badelek B, et al. Accurate measurement of F-2(d)/F-2(p) and R(d)-R(p). Nucl.Phys. B. 1997;487(1-2):3-26.Results are presented for F-2(d)/F-2(p) and R(d) - R(p) from simultaneous measurements of deep inelastic muon scattering on hydrogen and deuterium targets, at 90, 120, 200 and 280 GeV. The difference R(d) - R(p), determined in the range 0.002 0.1 the ratio decreases with Q(2)
The Q2 dependence of the structure function ratio F2Sn / F2C and the difference RSn-RC in deep inelastic muon scattering.
The A dependence of the nuclear structure function ratios
Arneodo M, Arvidson A, Badelek B, et al. The A dependence of the nuclear structure function ratios. Nucl.Phys. B. 1996;481(1-2):3-22.Results are presented for six nuclei from Be to Pb on the structure function ratios F-2(A)/F-2(C)(X) and their A dependence in deep inelastic muon scattering at 200 GeV incident: muon energy. The data cover the kinematic range 0.01 < x < 0.8 with Q(2) ranging from 2 to 70 GeV2. The A dependence of nuclear structure function ratios is parametrised and compared to various models
Measurement of density correlations in pseudorapidity via charged particle multiplicity fluctuations in Au+Au collisions at =200 GeV
331 authors, 32 pages text, RevTeX4, 7 figures, 27 tables. Submitted to Physical Review C. Plain text data tables for the points plotted in figures for this and previous PHENIX publications are (or will be) publicly available at http://www.phenix.bnl.gov/papers.htmlLongitudinal density correlations of produced matter in Au+Au collisions at sqrt(s_NN)=200 GeV have been measured from the inclusive charged particle distributions as a function of pseudorapidity window sizes. The extracted \alpha \xi parameter, related to the susceptibility of the density fluctuations in the long wavelength limit, exhibits a non-monotonic behavior as a function of the number of participant nucleons, N_part. A local maximum is seen at N_part ~ 90, with corresponding energy density based on the Bjorken picture of \epsilon_Bj \tau ~ 2.4 GeV/(fm^2 c) with a transverse area size of 60 fm^2. This behavior may suggest a critical phase boundary based on the Ginzburg-Landau framework
