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...

Bose - Einstein Correlations of Pion

A wavepacket model for a system of free pi-ons, which takes into account the full permutation symmetry of the wavefunction and which is suitable for any phase space parametrization is developed. The properties of the resulting mixed ensembles and the two-particle correlation function are discussed. A physical interpretation of the chaoticity as localization of the pions in the source is present...

Signal of Partial Ua(1) Symmetry Restoration from Two-pion Bose-einstein Correlations

In this conference contribution, we follow the lines of ref. 1 to show that a link exists between the symmetry properties of hot and dense hadronic matter and the strength of the two-pion Bose-Einstein correlation functions. In the chiral limit (mu = md = ms = 0), QCD possesses a U(3) chiral symmetry. When broken spontaneously, U(3) implies the existence of nine massless Goldstone bosons. In na...
