Parametrization of Bose-Einstein correlations and reconstruction of the source function in hadronic Z-boson decays using the L3 detector

Abstract

Bose-Einstein correlations of pairs of identical charged pions produced in hadronic Z decays are analyzed in terms of various parametrizations. A good description is achieved using a Lévy stable distribution in conjunction with a hadronization model having highly correlated configuration and momentum space, the τ-model. Using these results, the source function is reconstructed.

Bose-Einstein Correlations and the Tau Model

“…1a) and the Edgeworth parametrizations do a fair job [7,8] of describing the region Q < 0.6 GeV, but fail at higher Q, particularly the region 0.6-1.5 GeV where R 2 dips below unity, indicative of an anti-correlation. This is clearly seen in Fig.…”

“…Recently the l3 Collaboration has presented preliminary results showing that Eq. ( 13) describes their data on hadronic Z decay [33].…”
