On the m⊥-dependence of Bose-Einstein correlation radii
نویسنده
چکیده
Within a theoretical study using both HYLANDER and RQMD, we revisit Bose-Einstein correlation measurements of 200AGeV S+S and 160AGeV Pb+Pb. Transverse flow does not show up in the Bose-Einstein measurements. The decrease of the effective transverse radius parameters with increasing transverse average momentum of the particle pair is largely due to the effect of resonance decays. E.

Bose — Einstein correlations of charged kaons in p + p collisions with the STAR detector
We report the results of charged kaon Bose–Einstein Correlations (BEC) measured in protonproton collisions at √ s =200 and 510 GeV with the STAR detector at Relativistic Heavy Ion Collider (RHIC). The one-dimensional correlation functions are studied as a function of the charged particle multiplicity. The femtoscopic radii, R, and the correlation strength, λ, are extracted. The dependence of th...
متن کاملKaon HBT radii from perfect fluid dynamics using the Buda-Lund model
In this paper we summarize the ellipsoidally symmetric Buda-Lund model’s results on HBT radii. We calculate the Bose-Einstein correlation function from the model and derive formulas for the transverse momentum dependence of the correlation radii in the Bertsch-Pratt system of out, side and longitudinal directions. We show a comparison to √ sNN = 200GeV RHIC PHENIX two-pion correlation data and ...
متن کاملBOSE-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...
متن کاملRapidity dependence of Bose-Einstein correlations at SPS energies
This article is devoted to results on π−-π−-Bose-Einstein correlations in central Pb+Pb collisions measured by the NA49 experiment at the CERN SPS. Rapidity as well as transverse momentum dependences of the correlation lengths will be shown for collisions at 20A, 30A, 40A, 80A, and 158A GeV beam energy. Only a weak energy dependence of the radii is observed at SPS energies. The kt -dependence o...
متن کاملFine-Tuning Two-Particle Interferometry I: Effects from Temperature Gradients in the Source
A comprehensive model study of Bose-Einstein correlation radii in heavy ion collisions is presented. The starting point is a longitudinally and transversally expanding fireball, represented at freeze-out by an azimuthally symmetric emission function. The freeze-out temperature is allowed to feature transverse and temporal gradients. Their effects on the correlation radii are studied. In particu...
