Multiplicity, Jet, and Transverse Mass dependence of Bose-Einstein Correlations in e⁺e⁻- Annihilation

Abstract

Abstract. Bose-Einstein correlations of pairs of identical charged pions produced in hadronic Z decays are analyzed for both two-and three-jet events. A parametrization suggested by the τ-model is used to investigate the dependence of the Bose-Einstein correlation function on track multiplicity, number of jets, and transverse momentum.

Theτ-model of Bose-Einstein Correlations: Some recent results

“…The behavior of two-jet e + e − seems similar to pp, although the error bars are large. For both e + e − and pp, R is found [5,7] to increase with multiplicity (not shown). Further, for e + e − R is found [7] to increase with 'jettiness', as measured by y 23 .…”
