“…The PHENIX tracking system is optimized for the high multiplicity environment of ultra-relativistic heavy ion collisions. It comprises drift chambers (DC) [36] and pad chambers (PC1, PC2, and PC3) [37]. This analysis makes use of the first layer of pad chambers (PC1) and the third layer (PC3).…”

The transverse momentum (pT ) spectra and ratios of identified charged hadrons (π ± , K ± , p, p) produced in √ s N N = 200 GeV Au+Au and d+Au collisions are reported in five different centrality classes for each collision species. The measurements of pions and protons are reported up to pT = 6 GeV/c (5 GeV/c), and the measurements of kaons are reported up to pT = 4 GeV/c (3.5 GeV/c) in Au+Au (d+Au) collisions. In the intermediate pT region, between 2-5 GeV/c, a significant enhancement of baryon to meson ratios compared to those measured in p+p collisions is observed. This enhancement is present in both Au+Au and d+Au collisions, and increases as the collisions become more central. We compare a class of peripheral Au+Au collisions with a class central d+Au collisions which have a comparable number of participating nucleons and binary nucleon-nucleon collisions. The pT dependent particle ratios for these classes display a remarkable similarity, which is then discussed.

“…TABLE VI: Ratios of mesons to neutral pions in p+p collisions meson to pion ratios η/π 0 = 0.48 ± 0.03 [50] ρ/π 0 = 1.00 ± 0.30 [51] ω/π 0 = 0.90 ± 0.06 [52] η ′ /π 0 = 0.25 ± 0.075 [51] φ/π 0 = 0.40 ± 0.12 [51] Since the chosen approach of m T scaling ensures that at high p T the spectral shapes of all meson distributions are the same, the normalization of the meson spectra relative to the pion spectrum can be given by the ratios of mesons to pions at high p T (5 GeV/c is used here). The values used for p+p collisions are shown in Table VI.…”

Transverse momentum (p e T ) spectra of electrons from semileptonic weak decays of heavy flavor mesons in the range of 0.3 < p e T < 9.0 GeV/c have been measured at midrapidity (|η| < 0.35) by the PHENIX experiment at the Relativistic Heavy Ion Collider in p+p and Au+Au collisions at √ sNN = 200 GeV. In addition, the azimuthal anisotropy parameter v2 has been measured for 0.3 < p e T < 5.0 GeV/c in Au+Au collisions. The nuclear modification factor RAA with respect to p+p collisions indicates substantial energy loss of heavy quarks in the produced medium. Comparisons of RAA and v2 are made to various model calculations.

Principles of construction and structural and circuit designs of direct digital synthesizers based on the method of direct digital frequency and signal synthesis are described. The block and circuit diagrams of the direct digital synthesizer of compound wideband signals are presented. This synthesizer is used to synthe size signals with the amplitude, frequency, and phase modulation in a frequency range from 0.001 to 200 MHz.
