Search for the onset of baryon anomaly at RHIC-PHENIX

چکیده
The baryon production mechanism at the intermediate pT (2 5 GeV/c) at RHIC is still not well understood. The beam energy scan data in Cu+Cu and Au+Au systems at RHIC may provide us a further insight on the origin of the baryon anomaly and its evolution as a function of √ sNN . In 2005 RHIC physics program, the PHENIX experiment accumulated the first intensive low beam energy data in Cu+Cu collisions. We present the preliminary results of identified charged hadron spectra in Cu+Cu at

Excitation functions of baryon anomaly and freeze - out properties at RHIC - PHENIX
The intermediate p T region (2-5 GeV/c) in central Au+Au collisions at RHIC has a rich physics content. The (anti)proton to pion ratio at the intermediate p T gives us a powerful tool to investigate the bulk properties of the hot and dense matter created at RHIC and their hadronization processes. We present the preliminary results of identified charged hadron spectra at the lower beam energies ...
متن کاملThe role of jet quenching in the p̄ ≥ π − anomaly at RHIC
Preliminary PHENIX data on Au+Au reactions at √ s = 130 AGeV suggest that p̄ yields may exceed π− at high pT > 2 GeV/c. We propose that jet quenching in central collisions suppresses the hard PQCD component of the spectra in central A + A reactions, thereby exposing a novel non-perturbative component of baryon dynamics. We suggest that baryon junctions provide a possible explanation of the anoma...

The PHENIX experiment at RHIC has extended its scope to cover spin physics using polarized proton beams. The major goals of the spin physics at RHIC are elucidation of the spin structure of the nucleon and precision tests of the symmetries. Sensitivities of the spin physics measurements with the PHENIX detector system are reviewed. The Relativistic Heavy Ion Collider (RHIC) is under constructio...
متن کاملThe PHENIX Potential in the Search for the QCD Critical Point
With the measurement of several observables at SPS energies that demonstrate non-monotonic behavior as a function of centrality and √ sNN , there is growing interest in pursuing a scan of relativistic heavy ion collisions at low energies at the Relativistic Heavy Ion Collider. The capabilities of the PHENIX experiment to take quality measurements at low RHIC energies is described and directly d...
متن کاملJet Correlations with Identified Particles from PHENIX : Methods and Results
Azimuthal angle two particle correlations have been shown to be a powerful probe for extracting novel features of the interaction between hard scattered partons and the medium produced in Au+Au collisions at RHIC. At intermediate pT , 2-5GeV/c, the jets have been shown to be significantly modified in both their particle composition and their angular distribution compared to p+p collisions. Addi...
