L\'evy-stable Two-pion Bose--Einstein Correlation Functions Measured with PHENIX in $\sqrt {s_{NN}} =$ 200 GeV Au+Au Collisions

Pion Interferometry in Auau Collisions at √ S Nn =200 Gev

We present preliminary results from a two-pion intensity interferometry analysis from Au+Au collisions at √ s NN =200 GeV measured in the STAR detector at RHIC. The dependence of the apparent pion source on multiplicity and transverse momentum are discussed and compared with preliminary results from d+Au and p+p collisions at the same beam energy.

BOSE-EINSTEIN CORRELATIONS IN PION PRODUCTION AT TRISTAN

Measurement of Bose-Einstein correlations in the production of like-signed pion pairs has been made with the AMY detector at TRISTAN. An event sample of 10120 hadronic events with ranging between 50 to 61 GeV was used. These measurements indicate a strength of the enhancement of ? = 0.61M.07, with a typical correlation size of Ro = 1.16±.08 fm. This value of ? is consistent with measurem...

Measurement of the neutral pion cross section in proton - proton collisions at √ s = 200 GeV with PHENIX

The inclusive cross section for neutral pion production in the range 1 < p T < 13 GeV/c in |η| < 0.35 has been measured by the PHENIX experiment in proton-proton collisions at √ s = 200 GeV. An NLO pQCD calculation is, within the experimental and theoretical uncertainties, consistent with the measurement.
