STAR Correlations and Fluctuations PWG

[Xiaofeng Luo <xfluo.star AT hotmail.com>]

    Hi Chuan,
        
        Nice presentation.
        Thank you for addressing Hanna's suggestions/comments. 
        I have no further suggestions.  
        I sign off. 
    
        Enjoy the conference !
    
    Thank you, 
    Best Regards,
    Xiaofeng
