  The L3 Collaboration reported data on 2-jet and 3-jet Bose-Einstein
correlations (BECs) with the results obtained through the $\tau$-model in 2011.
In this study, we analyze these correlations using the conventional formula
with the Gaussian long-range correlation (${\rm CF\times LRC_{(Gauss)}}$). The
estimated ranges of interactions for 2-jet and 3-jet, $R_{\rm 2-jet}$ and
$R_{\rm 3-jet}$, have almost the same magnitude as those by $\tau$-model:
$R_{\rm 2-jet}=0.83\pm 0.05$ fm and $R_{\rm 3-jet}=1.09\pm 0.04$ fm. The
anticorrelation in BEC (less than 1.0) observed by the L3 Collaboration is
related to the partially negative density profile ($\rho_{\rm \tau, BE}(\xi)$
in $\xi$ space) in the $\tau$-model and the ${\rm LRC_{(Gauss)}}=1/(1+\alpha
e^{-\beta Q^2})$ in ${\rm CF_I\times LRC_{(Gauss)}}$, respectively. Remarkably,
the probability $P_{\tau}(\xi)$ calculated from the Levy canonical form
exhibits partially negative behavior.
