چکیده
Back-to-back hadron pair yields in d+Au and p+p collisions at √s(NN)=200 GeV were measured with the PHENIX detector at the Relativistic Heavy Ion Collider. Rapidity separated hadron pairs were detected with the trigger hadron at pseudorapidity |η|<0.35 and the associated hadron at forward rapidity (deuteron direction, 3.0<η<3.8). Pairs were also detected with both hadrons measured at forward rapidity; in this case, the yield of back-to-back hadron pairs in d+Au collisions with small impact parameters is observed to be suppressed by a factor of 10 relative to p+p collisions. The kinematics of these pairs is expected to probe partons in the Au nucleus with a low fraction x of the nucleon momenta, where the gluon densities rise sharply. The observed suppression as a function of nuclear thickness, p(T), and η points to cold nuclear matter effects arising at high parton densities.

Forward Physics at Star Status of Analysis on Forward and mid Rapidity Correlation Measurements in P+p and D+au
Measurements of the production of high energy π mesons at large pseudorapidity, coincident with charged hadrons at mid-rapidity, for proton+proton and deuteron+gold collisions at √ sNN = 200 GeV are reported. The p+p cross section for inclusive π production follows expectations from next-to-leading order perturbative QCD. Both the inclusive cross section and the di-hadron azimuthal correlations...

STAR has measured forward π 0 production in p+p and d+Au collisions at √ s NN = 200 GeV. The p+p yield generally agrees with NLO pQCD calculations. The d+Au yield is strongly suppressed at η = 4.0, well below shadowing expectations. Exploratory measurements of azimuthal correlations between forward π 0 and mid-rapidity charged hadrons show a recoil peak in p+p that is suppressed in d+Au at low ...
متن کاملJet-Like Correlations between Forward and Mid-Rapidity
Mid-rapidity azimuthal correlations probe di-jets originating mainly from gluongluon hard-scattering. Measurements of such correlations have revealed significant (gluon-)jet modification in central Au+Au collisions. Azimuthal correlations at forward rapidity with a mid-rapidity high-pT hadron, on the other hand, are sensitive primarily to quark-gluon hard-scattering and may probe quark-jet modi...

PHENIX has measured transverse momentum spectra of charged particles at mid-rapidity up to 10 GeV/c in Au+Au collisions at √ s nn = 200 GeV. For central collisions, the yield at high p T is significantly suppressed comparing to binary scaled p+p data, and this suppression is stronger than observed at 130 GeV [1,2]. Above 4 GeV/c, the deficit of high momentum particles is almost independent of p...
