- Abstract
In this paper, we can obtain a second conventional formula ( CF II ) with two components by extending the conventional formula CF I with one component for Bose–Einstein Correlation (BEC). We used CF II to analyze the BEC at Z 0 -pole as part of the OPAL collaboration. R 1 (G) = 0. 9 1 ± 0. 0 3 fm ( λ 1 = 0. 6 1 ± 0. 0 3) and R 2 (G) = 2. 5 7 ± 0. 4 4 fm ( λ 1 = 0. 3 5 ± 0. 0 9) are the estimated interaction region, where λ 1 and λ 2 are the degrees of coherence, and G is the Gaussian distribution, respectively. Long-range correlation (LRC) is also studied.
