1.Introduction Semi-inclusive events If these distributions are constructed from the same data samples, Parameters on the BEC (cf. source radius, which is estimated from the 2-body BEC) are included in the multiplicity distribution. • 2-particle Bose-Einstein correlation function • Multiplicity distribution • One-particle momentum density • Two-particle momentum density
3-2.Multiplicity distribution in the QO approach • KNO scaling function The MD is approximately given by the Glauber-Lachs formula.
4-2. Analysis of BEC ALICE collaboration Phys. ReV. D84,112044(2011) pp 7 TeV, |η|<1.2 • q-long distribution : • q-side distribution :
5. Summary • q-long distribution :
