STAR HardProbes PWG

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

Hi Youqi,

Thanks a lot for the updated version and reply. I don't have any further comments on your nice slides. 

Just want to follow up the HERWIG7, I understand it has different hadronization and it is (probably) okay to compare it with. But can you really draw a conclusion from this comparison? I mean, can you tell the difference is due to different collision energy or hadronization process? If not, I am not sure how helpful this comparison can be. Just my two cents. 

Cheers,

Yi

Hi Barbara, Nihar and Yi,

Thanks for the feedback! I have updated my slides here: https://drupal.star.bnl.gov/STAR/system/files/dis_032823_v3.pdf

Regarding Barbara's comments:

Just a comment on s16. It's hard to quickly judge by eye which distribution is more steep so it might not be obvious to people. But you don't need the right plot to make this point. The first split should be basically the sum of the contributions that you show on your plot. So naturally it should be less steep than the blue, if green and yellow are flatter. With the z_g in R_g bins we show that we saw the np contributions to the first split and have a consistent picture - as you write in your backup. Which I think is a nice physics message. 

I see, that's a good point. I switched the zg vs Rg plot into the main section and zg vs # splitting to backup. 

Regarding Nihar's comments:

I have fixed the wording and updated my figures here: https://drupal.star.bnl.gov/STAR/blog/youqi/Multidimensional-jet-substructure-multifold-preliminary-figures.

Regarding Yi's comments:

 - p2: your right-handed cartoon plot covers the text a bit. 

 - p3: the resolution at the left-bottom area (z_g, z_cut, and beta) is not good? And similar for dM/M and M on p4. 

I fixed these in the new version.

 

 - p6: What does "~" mean here? I saw 3 places. 

 I use "~" to indicate something like "roughly implies/looks like". We wanted to be careful here because hadronization effects can affect our measurements. I added a note about that on this slide.

 - p12: Could you please remind me of the motivation for comparing HERWIG with LHC tune? Do we expect the tune works for RHIC? 

We don't have a HERWIG tune at RHIC energy, and this LHC tune that we used is the default tune in HERWIG7. I think it's still useful to compare since it does hadronization differently from PYTHIA.

 

 - p14: the "boxes (yellow, green, and black)" cover the information on the plot, could you please try a thinner line for them? 

I have my slides in animation, so when the left side 2D plot first shows up, those boxes are not there. I will keep them for my presentation, but perhaps when I upload the slides to the indico page I can remove those boxes.

Best,

Youqi

Hi Youqi,

Thanks a lot for the nice slides. I only have some minor comments for your consideration.

 - p15: I am not sure if it is good to say "See Monika's talk at HP", probably is okay...

Cheers,

Yi
