نویسنده
چکیده
In 2001, PHENIX measured particle correlations of identical charged pions and kaons at mid-rapidity in Au-Au collisions at √ s N N = 200 GeV. Bertsch-Pratt radius parameters of pion pairs are studied for 9 k T regions from 0.2 to 2.0 GeV/c and for 9 selections of collision centralities. The pion radius parameters are consistent with the result at √ s N N = 130 GeV, and the ratio R out /R side is below 1 in all k T ranges up to 1.2 GeV/c. The radius parameters from charged kaon correlations are compared with those of pions.

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...

The PHENIX detector at RHIC measured high p T identified hadron ratios in √ s N N = 200 GeV Au+Au collisions. Within the current systematic and statistical errors, p/p ratios that are measured up to 3.8 GeV/c are almost independent of both p T and centrality. The baryon to meson ratio is measured through p/π and p/π ratios up to 3.8 GeV/c, showing they are strongly centrality dependent.

Inclusive transverse momentum spectra of single electrons from Au+Au collisions have been measured at √ s N N = 130 GeV and 200 GeV at midrapidity by the PHENIX experiment at RHIC. After subtraction of background from photon conversions and light hadron decays, the spectra appear consistent with semileptonic decays of charmed particles.

We give the emission function of the axially symmetric Buda-Lund hydro model and present its simultaneous, high quality fits to identified particle spectra, two-particle Bose-Einstein or HBT correlations and charged particle pseudorapidity distributions as measured by BRAHMS and PHENIX in 0-30 % central, √ sNN = 200 GeV Au+Au collisions at RHIC. The best fit is achieved when the most central re...

The PHENIX collaboration has developed novel methodologies for reliable extraction of jet functions from two and three particle azimuthal correlation functions measured at mid-rapidity in Au+Au collisions at √ s = 200 GeV. The extracted jet shape and the yield of jet-associated partner hadrons (per trigger hadron) are found to vary with particle type and collision centrality, indicating a signi...
