On the Normalisation and Subtraction Methods Applied to the OPAL 3π Bose-Einstein Correlations
نویسندگان
چکیده
The study of the so called “genuine” Bose-Einstein correlations (BEC) of three identical charged pions requires the subtraction of the 2nd order BEC of the pion pairs. The OPAL subtraction method used in the BEC study of the π±π±π± system, which utilised mixed charged pions triplets of the data themselves, is investigated in detail. The derivation of the subtraction formula is explained.

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...

The studies of Fermi–Dirac correlations of ΛΛ and ¯ Λ ¯ Λ pairs in hadronic Z decays, Bose–Einstein correlations and colour reconnection in W-pairs decays performed by the ALEPH collaboration in e + e − annihilation at LEP are presented. The OPAL analysis of Bose–Einstein correlations in W-pair decays is also discussed.

Using effective formulas we analyze the Bose-Einstein correlations (BEC) data corrected for Coulomb interactions provided by STAR Collaboration and the quasicorrected data (raw data with acceptance correction etc) on 2π and 3π BEC by using Coulomb wave function with coherence parameter included. The corresponding magnitudes of the interaction regions turn out to be almost the same: RCoul(2π) ≃ ...
