Hi Yi, 

Thank you for the feedback!  I have uploaded an updated version and addressed your comments below.

 - p4: Are the sub-bullet for the 3rd bullet and the 4th bullet the same? 

Yes, I have removed that redundancy.

 - p6: toy mode --> toy model 

Fixed.

 - p9: Just for my own education, could you please tell me why A_j can be less than 0 (I am assuming pT^1 and pT^2 are leading and subleading jet pT, respectively, is it correct)? 

Yes, (pT^1, pT^2) is the (leading, subleading) jet pT.  The red points are the measurement of A_j using only hard cores.  This is where leading and subleading are determined, thus no points below 0.  However, after matching is done, leading and subleading are not recalculate, so it is possible for the subleading hard core to match to a jet with more momentum than the leading hard core does, resulting in negative A_j.  There are a few ways this could happen.  The subleading jet could contain a larger soft component than the leading jet, thus when added to the hard core the magnitudes flip.  Additionally, because of the fluctuating background the leading jet could be over subtracted and the subleading jet under subtracted, again flipping the relative magnitude.  This would not affect the hard core since background subtraction is not done on that collection.

 - p15: It would be good if you can provide more information for the subdetectors, for example eta and phi coverage... 

I added more information about each system and labeled the picture.

 - p18: Jet v2 not feasible --> Jet v2 is not feasible 

Changed to Jet v2 was not feasible

Cheers,

Tristan

Hi Tristan,

Thanks a lot for the nice slide. I have some suggestions/comments for your consideration. 

 - p4: Are the sub-bullet for the 3rd bullet and the 4th bullet the same? 

 - p6: toy mode --> toy model 

 - p8: Title: Hardcore --> Hard core

 - p9: Just for my own education, could you please tell me why A_j can be less than 0 (I am assuming pT^1 and pT^2 are leading and subleading jet pT, respectively, is it correct)? 

 - p15: It would be good if you can provide more information for the subdetectors, for example eta and phi coverage... 

 - p18: Jet v2 not feasible --> Jet v2 is not feasible 

 - Since we are not settled with your preliminary results yet, I will comment on p20 and p21 later. :-) 

Cheers,

Yi

Hi All,

I submitted this material for review last week, but it seems to have been lost somehow, so I am resending it.

Cheers,

Tristan
