Centrality dependence of charged-particle pseudorapidity distributions from d + Au collisions at sqrt[sNN] = 200 GeV.
Charged-particle pseudorapidity densities are presented for the d + Au reaction at sqrt[s(NN)] = 200 GeV with -4.2 < or = eta < or = 4.2. The results, from the BRAHMS experiment at BNL Relativistic Heavy-Ion Collider, are shown for minimum-bias events and 0%-30%, 30%-60%, and 60%-80% centrality classes. Models incorporating both soft physics and hard, perturbative QCD-based scattering physics a...
متن کاملCharged particle jet measurements with the ALICE experiment in proton-proton collisions at the LHC
We present preliminary results of measurements of charged particle jet properties in proton-proton collisions at √ s = 7 TeV using the ALICE detector. Jets are reconstructed using anti − kT, kT and SISCone jet finding algorithms with resolution parameter R = 0.4 in the range of transverse momentum from 20 to 100 GeV/c in the midrapidity region (| η | < 0.5). The uncorrected charged jet spectra ...
متن کاملInclusive Pseudorapidity Distributions in p(d)+A Collisions Modeled With Shifted Rapidity Distributions
We study the recent PHOBOS data on the pseudorapidity density of inclusive charged particles in centrality-binned d+Au collisions at √ sNN = 200 GeV. It appears that one can understand the increasing forward-backward asymmetry in the data by assuming that the entire distribution “shifts” backwards in rapidity according to the initial-state kinematics, while the total multiplicity scales linearl...
متن کاملCharged particle identification in the ALICE experiment
A key feature of the ALICE experiment will be the capability to identify the charged particles in the full range of momentum thus allowing to investigate the properties of the quark-gluon plasma during its dynamical evolution toward the freeze-out phase when the re-hadronization occurs. Low momentum hadron identification will be achieved via measurements of energy loss in the silicon layers of ...
متن کاملThree-particle coincidence of the long range pseudorapidity correlation in high energy nucleus-nucleus collisions.
We report the first three-particle coincidence measurement in pseudorapidity (Δη) between a high transverse momentum (p⊥) trigger particle and two lower p⊥ associated particles within azimuth |Δϕ|<0.7 in square root of s(NN)=200 GeV d+Au and Au+Au collisions. Charge ordering properties are exploited to separate the jetlike component and the ridge (long range Δη correlation). The results indicat...
