STAR HardProbes PWG

[Barbara Trzeciak <barbara.trzeciak AT gmail.com>]

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.
https://journals.aps.org/prd/abstract/10.1103/PhysRevD.92.094007
Derek, Please include this one as a reference.

Cheers
