Dear Prithwish,

Hello thank you for your kind sign-off. Please find my updated slides including your nice comments in https://drupal.star.bnl.gov/STAR/system/files/DNP_Oct_STAR_SBU_ChunjianZhang_v1.pdf

Hi Chunjian,
 Nice slides:
https://drupal.star.bnl.gov/STAR/system/files/DNP_Oct_STAR_SBU_ChunjianZhang_v0.pdf

Please see my comments below. With these included, I sign-off.

slide#1:
I think it's always a great idea to spell out your institution name below your name. Also your name doesn't have to be written in too small font like you have now.

Very Nice comments. Thank you. There is the only chance to show the SBU logo in the first slide. So I keep this and make it simple and symmetric. Otherwise we will have two “Stony Brook University”. 

slide#2:
The right most cartoon is not "Freeze Out" its more like “Detection”

Somehow the Freeze-out is also make sense. “It contains chemical freeze out from hadronization and kinetic freeze out after evolution"

slide#2:
"pressure gradient forces" --> "pressure gradients”

done 

slide#2:
"The shape of the size of the overlap is directly controlled by the shape..colliding nuclei" --> "The shape and the size of the overlap is controlled by the shape...colliding nuclei, most dominantly in central collisions.

I will say it during the presentation to avoid the long words happening in the slides 

slide#3:
In the equation of \rho(r,\theta,φ), a parenthesis ")" is missing in the exponential

Done 

slide#3:
"Final Particle Flow" --> "Produced Particle Flow”

done 

slide#3:
"Harmonic flow" --> "Anisotropic flow”

done 

slide#4:
"is just shape" --> "is related to the shape

Done 

slide#4:
"Harmonic flow" --> "Harmonic flow coefficient”

done 

slide#4:
This sentence is unclear: "R_\perp is related to Y_2^0 projected to the transverse plane". R_\perp is related to which aspect of Y_2^0? It's magnitude ?

The overlap region in transverse plane depends on Euler angle. from the It’s from the arXiv 2109.00604 page 24.  

slide#4:
Equation of "R_\perp^2 = <x^2> +<y^2> =<...>" I don't understand how this works. The term inside <...> is dimensionless because spherical harmonics are dimensionless where as R, x, y are not. Something is missing here.

The overlap region in transverse plane depends on Euler angle. from the It’s from the arXiv 2109.00604 page 24.  

slide#4:
Please increase the font of the sentence starting with "fluctuation of …."

Done

slide#5:
Much of what you write on this slide is related to search for CME. The sentence starting with "A precision.." is not needed for your talk. But please somewhere write "Isobar run originally dedicated to CME search". You can also refer to Sergei's talk for more details but that is optional.

I will speak the words during my talk to avoid the busy slides with many words and I also include Sergei’s talk with a short index .

Session CA(Oct. 11): CME search at STAR (Sergei A Voloshin )

"

slide#6:
"Deviate from unity from mid-central" --> "Deviate from unity in mid-central collisions”

Done

slide#6:
"Request for more and finer bins" --> "Goal is to explore this in finer bins of multiplicity”

Done

slide#7:
"deformation using heavy ion collisions" -->"deformation in heavy ion collision measurements”

Done

slide#8:
Title "variance ratio" --> "[pT]-variance ratio”

done 

slide#8:
"also could be used in conjunction with anisotropy" -->"could also be used in conjunction with anisotropic”

Done

slide#9:
"The large difference of v_2 and v_3 suggests" --> "The large difference of v_2 and v_3 in central isobar collisions”

Done

slide#9:
"[pT] fluctuations also could be used in conjunction with anisotropy flow on the deformation study conclusion are consistent"
-->
"[pT] fluctuations also sensitive to deformation study leads to consistent conclusion:”

Done

slide#9:
"Opportunity to study on nuclear structure at a much shorter scale (~10^-24 s)"
-->
"Opportunity to study nuclear structure at very short time scale (~10^-24 s) accessible through heavy ion collisions”

Done 

slide#9:
"A lot of possibility for scan." -->"A future deformed-system scan will be ideal.”

Done 

slide#9:
"But need to first establish the heavy ion systematics using species with known deformation"
-->
"Species with well known deformation will be useful to better understand the systematics and establish the efficacy of this approach”

Done 

Best,
Prithwish
