Dear Chunjian,

I sign off and sending your slides to star-talks with a comment:

s#5: fix the text overlap in bullet 2.

Thanks and regards,

Hi Chunjian,
I see that you've mistakenly selected "APS meeting" instead of
"WPCF". Here are my comments on your nice slides for WPCF:
slide#5:
"Direct indication and well constrain the nuclear deformation"
-->
"Direct indications and well constraints on nuclear deformation"
Slide#7:
These are new results. The conclusion lines are not clear.
Are you trying to say that the linear part (v_2L) of v_4 is not
expected to be affected by quadrupole and octupole deformation but
the non-linear part (v_NL) can be affected by quadrupole deformation
through v_2? Also, v_2 ration depends on a0, R etc. so will the
v_4NL. And the current data are consistent with such expectations.
Although uncertainties are large to conclude the effect of \beta_2
in v_4NL, the effects of a0 and R0 maybe is conclusive from the
data. I don't think any of these are clear from the slide so you
have to spend some time during your talk.
How about writing :
v_4L ~ \epsilon (4), no strong dependence on \beta_2 and \beta_3
which affect \epsilon (2) & \epsilon (3), respectively
v_4NL ~ v_2^4 ~ (\epsilon (2))^4, therefore affected by \beta_2, a0
and R.
"Results are consistent with the expectations of hydrodynamic mode
coupling of flow harmonics & effects of a0, R0 in non-central
collisions"
Slide#8:
"Central collisions reflect the nuclear structure effect but signals
near to 0 with large relative statistics"
-->
"SC2,3 show hint of deviation from unity near central collisions as
expected from nuclear structure effects -- measurement uncertainties
dominate"
Slide#9-13 include results shown before so I don't have any major
comments. "Flow-[pT]" --> "Flow - transverse momentum" or "v_n -
[pT]" ?
Conclusion:
"The nonmonotonic trend.." --> "The non-monotonic trend with N_ch.."
Best,
Prithwish
