This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We determine rapidity asymmetry in the production of charged pions, protons and anti-protons for large transverse momentum (p{sub T}) for d+Au collisions at √s{sub NN} = 200 GeV. The rapidity asymmetry is defined as the ratio of particle yields at backward rapidity (Au beam direction or -ve rapidity) to those at forward rapidity (d beam direction or +ve rapidity). The identified hadrons are measured in the rapidity regions.

This book was released on 2011 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have carried out a wide study of Cold Nuclear Matter (CNM) effects on J/[Psi] = production in dAu, CuCu and AuAu collisions at √s{sub NN} = 200 GeV. We have studied the effects of three different gluon-shadowing parameterizations, using the usual simplified kinematics for which the momentum of the gluon recoiling against the J/[Psi] is neglected as well as an exact kinematics for a 2 → 2 process, namely g + g → J/[psi] + g as expected from LO pQCD. We have shown that the rapidity distribution of the nuclear modification factor R{sub dAu}, and particularly its anti-shadowing peak, is systematically shifted toward larger rapidities in the 2 → 2 kinematics, irrespective of which shadowing parameterization is used. In turn, we have noted differences in the effective final-state nuclear absorption needed to fit the PHENIX dAu data. Taking advantage of our implementation of a 2 → 2 kinematics, we have also computed the transverse momentum dependence of the nuclear modification factor, which cannot be predicted with the usual simplified kinematics. All the corresponding observables have been computed for CuCu and AuAu collisions and compared to the PHENIX and STAR data. Finally, we have extracted the effective nuclear absorption from the recent measurements of RCP in dAu collisions by the PHENIX collaboration.

Book excerpt: Identified mid-rapidity particle spectra of [pi]{sup ±}, K{sup ±}, and p({bar p}) from 200 GeV p+p and d+Au collisions are reported. A time-of-flight detector based on multi-gap resistive plate chamber technology is used for particle identification. The particle-species dependence of the Cronin effect is observed to be significantly smaller than that at lower energies.

Book Synopsis Identified Particle Transverse Momentum Distributions from AU + AU Collisions at 62.4 GeV Per Nucleon Pair by : Conor Henderson
Download or read book Identified Particle Transverse Momentum Distributions from AU + AU Collisions at 62.4 GeV Per Nucleon Pair written by Conor Henderson and published by . This book was released on 2005 with total page 322 pages. Available in PDF, EPUB and Kindle. Book excerpt: Transverse momentum (PT) distributions for pions, kaons, protons and antiprotons have been measured near mid-rapidity for Au+Au collisions at sNN = 62.4 GeV using the PHOBOS detector at the Relativistic Heavy-Ion Collider (RHIC) in Brookhaven National Laboratory. Particle identification is performed using the PHOBOS Time-of-Flight plastic scintillator walls and specific energy loss in the multi-layer silicon Spectrometer, which is also used for track reconstruction and momentum-determination. The spectra are corrected for all detector-dependent effects, including feed-down from weak decays. At PT 3 GeV/c, protons are measured to be the dominant species of charged hadrons and scale much faster with respect to collision centrality than mesons. This behaviour at 62.4 GeV is found to be remarkably similar to that observed in Au+Au collisions at 200 GeV, an interesting observation which should serve as an important constraint on the various mechanisms which have been proposed to describe particle production over this PT range. Baryon stopping, the transport of baryon number from intial beam rapidity, is explored through the net proton (p - p) yields at mid-rapidity. These results fill a large gap between the SPS and higher RHIC energies and as such form an important set of data for comparing to models of baryon transport mechanisms.
Book Synopsis PHENIX Results on Centrality Dependence of Yields and Correlations in D Plus Au Collisions at Root S(NN) by :
Download or read book PHENIX Results on Centrality Dependence of Yields and Correlations in D Plus Au Collisions at Root S(NN) written by and published by . This book was released on 2016 with total page 6 pages. Available in PDF, EPUB and Kindle. Book excerpt: PHENIX has measured the transverse momentum (pT) spectra and two particle angular correlations for high pT particles in d+Au collisions at psNN=200 GeV using the RHIC Year-2008 run data. The azimuthal angle correlations for two particles with a large rapidity gap exhibit a ridge-like structure. Using the pi-0s reconstructed in the EMCal, we have successfully extended the pT reach of the correlation up to 8 GeV/c. We find that the azimuthal anisotropy of hadrons found at low pT persists up to 6 GeV/c with a significant centrality and pT dependence, similar to what was observed in A+A collisions.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The pseudorapidity asymmetry and centrality dependence of charged hadron spectra in d+Au collisions at (square root)s{sub NN} = 200 GeV are presented. The charged particle density at mid-rapidity, its pseudorapidity asymmetry and centrality dependence are reasonably reproduced by a Multi-Phase Transport model, by HIJING, and by the latest calculations in a saturation model. Ratios of transverse momentum spectra between backward and forward pseudorapidity are above unity for p{sub T} below 5 GeV/c. The ratio of central to peripheral spectra in d+Au collisions shows enhancement at 2

Available in PDF, EPUB and Kindle. Book excerpt: We have studied the[ital J]/[psi] production in[ital p][ital[anti p]] collisions at[radical]s= 1.8 TeV with the D[null] detector at the Fermilab Tevatron, using a[mu][sup+][mu][sup -] data sample collected during the 1994-95 running period. We have measured the inclusive[ital J]/[psi] production cross section as a function of the[ital J]/[psi] transverse momentum, [ital P][sub T][sup[ital J]/[psi]] in the central and forward rapidity regions. The new measurement of the cross section[ital d[sigma]/dp][sub T][sup[ital J]/[psi]] for[vert-bar][eta][sup[ital J]/[psi]][vert-bar][lt] 0.6 is in a good agreement with the CDF and earlier D[null] results. The cross section measurement[ital d[sigma]/dp][sub T][sup[ital J]/[psi]] for 2.5[lt][vert-bar][eta][sup[ital J]/[psi]][vert-bar][lt] 3.7 covers the[ital p][sub T][sup[ital J]/[psi]] range from 1 to 16 GeV/c. We combine the measurements in several[vert-bar][eta][sup[ital J]/[psi]][vert-bar] regions to discuss[ital d[sigma]/d[eta]][sup[ital J]/[psi]] for[ital p][sub T][sup[ital J]/[psi]][gt] 8 GeV/c. The data are compared with the next-to- leading order (NLO) QCD calculations, which take into account different[ital J]/[psi] production mechanisms.

Download or read book Identified Particle Production, Azimuthal Anisotropy, and Interferometry Measurements in Au+Au Collisions at Sqrt SNN written by and published by . This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present the first measurements of identified hadron production, azimuthal anisotropy, and pion interferometry from Au+Au collisions below the nominal injection energy at the Relativistic Heavy-Ion Collider (RHIC) facility. The data were collected using the large acceptance STAR detector at (square root)s{sub NN} = 9.2 GeV from a test run of the collider in the year 2008. Midrapidity results on multiplicity density (dN/dy) in rapidity (y), average transverse momentum (p{sub T}), particle ratios, elliptic flow, and HBT radii are consistent with the corresponding results at similar (square root)s{sub NN} from fixed target experiments. Directed flow measurements are presented for both midrapidity and forward rapidity regions. Furthermore the collision centrality dependence of identified particle dN/dy, p{sub T}, and particle ratios are discussed. These results also demonstrate that the capabilities of the STAR detector, although optimized for (square root)s{sub NN} = 200 GeV, are suitable for the proposed QCD critical point search and exploration of the QCD phase diagram at RHIC.

This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: We present STAR measurements of the azimuthal anisotropy parameter v2 and the binary-collision scaled centrality ratio R{sub CP} for kaons and lambdas ([Lambda] + {bar [Lambda]}) at mid-rapidity in Au+Au collisions at √s{sub NN} = 200 GeV. In combination, the v2 and R{sub CP} particle-type dependencies contradict expectations from partonic energy loss followed by standard fragmentation in vacuum. We establish p{sub T} ≈ 5 GeV/c as the value where the centrality dependent baryon enhancement ends. The K{sub S}° and {Lambda} + {bar {Lambda}} v2 values are consistent with expectations of constituent-quark-number scaling from models of hadron formation by parton coalescence or recombination.

This book was released on 1994 with total page 5 pages. Available in PDF, EPUB and Kindle. Book excerpt: The NA35 experiment has collected a high statistics set of momentum analyzed negative hadrons near and forward of mid-rapidity for central collisions of 200 GeV/Nucleon 32S projectiles incident on S, Ag and Au targets. Using two pion momentum space correlations in order to study the size of the source of particle production, small dependences upon transverse momentum are found for the transverse source dimensions; however for the heaviest system, R{sub long} decreases by about 40% as transverse momentum is increased over the interval 50

Available in PDF, EPUB and Kindle. Book excerpt: Inclusive transverse momentum spectra of photons and[pi][sup 0]s at mid-rapidity are studied as a function of collision centrality for[sup 197]Au+[sup 197]Au collisions at[radical]s[sub NN]= 130 GeV. Photon pair conversions have been reconstructed from charged tracks measured by the main Time Project Chamber of the STAR experiment at the RHIC heavy ion facility. The transverse momentum resolution of photons with this method is estimated to be[Delta]p[sub t]/p[sub t]= 2% at 0.125 GeV/c and 5% at 2.5 GeV/c. Photon spectra were measured up to a transverse momentum of 2.4 GeV/c between[+-] 0.5 units of rapidity. The dominant photon production mechanism, the[pi][sup 0][yields][gamma][gamma] decay, was measured between 0.25-2.5 GeV/c and[+-] 1 units of rapidity. Spectra are reported for the top 11%, 11-34% and 34-85% centrality classes. It was observed that in mid-central and central collisions the relative contribution of the[pi][sup 0][yields][gamma][gamma] decay to the inclusive photon spectrum decreases above a transverse momentum of 1.65 GeV/c. In central collisions the magnitude of the decrease from p[sub t]= 1.65 GeV/c to 2.4 GeV/c is 20%. It is unlikely that contributions from other[pi][sup 0] decay channels and other particle decays fully explain this decrease. The centrality dependence on the shapes of the[pi][sup 0] spectra was analyzed with Boltmann and Bose-Einstein functions. In the transverse momentum windows of the spectra, the extracted temperatures are near 0.295 GeV. These temperatures are substantially higher than those extracted from[pi][sup[+-]] spectra in a lower range of transverse momentum. This is an indication that the shapes of the pion spectra deviate from purely exponential shapes.
