STAR Correlations and Fluctuations PWG

[Nu Xu <nxu AT lbl.gov>]

Dear Daniel and All,

Thank you for the quick responses.
Regarding to the first reply to my first point, I am still not convinced.
Two particle correlations do not ‘see' the density because it only be 
effective when the strong interactions are ceased. Source size parameters do 
not reflected direct the size ( -> density) due to other effects such as 
collective flow.

The claim of density effect could be misleading.

Regards,
Nu
