STAR HardProbes PWG

[Yi Yang <yiyang AT ncku.edu.tw>]

Hi Yan,

Somehow I missed your email, sorry about that and thanks a lot for the nice slides. 

I only have some minor comments on v4 for your consideration. 

  - Title page: I would move "sqrt(s_NN) = " to the next line. 

  - p3: RAA --> Nuclear modification factor (RAA)   (it would be better to write down the definition here) 

          v2 --> Elliptic flow (v2)   (It would be also good to write down the formula here) 

  - p10: Polynomial 3 --> 3rd order polynomial 

  - p12: with current statistics 

  - p13: Isobar --> isobar 

  - p14: v2 is consistent with zero   (remove at low pT)

Cheers,

Yi
