STAR HardProbes PWG

[Sooraj Radhakrishnan <skradhakrishnan AT lbl.gov>]

Hi Derek,

   Thanks for the update and taking into account the suggestions. The figures are also better placed in the version. Just one comment to the new version. 

L 127 - 129, L 150: 'angular scale of intreajet broadening is about 0.5 radians' - how do you make this conclusion? You dont show any shapes and from the RAA it seems difficult to evaluate the size of broadening 

thanks

Sooraj

Hi Derek,

I have minor remaining comments and sign off your nice proceedings.

L58/59: 10 nb−1 should be in the same line

L106, 120: should it be p_{T,jet }^{reco,ch} or p_{T,jet }^{ch} ? 

L122: lower panel -> upper panel

L123: upper panel -> lower panel

L135:  p_{T,jet }^{reco} -> p_{T,jet }^{ch}

Cheers,

Barbara

Hello Derek and Yi,

This is the reference for Sudakov resumption.

Derek, Please include this one as a reference.
