Hello Qian,

Please find my comments on your nice presentation slides.

SLide-4:
Not sure, what is the purpose of left figure?
Left side theory plot is for J/psi polarization in jet where as right 
side is for inclusive J/psi polarization.
There are different. The comparison may not be correct. Is not it?

Besides, Left figure for x-axis J/psi FF (zh) where as the right data 
plot x-axis is Jpsi pT.
I understand the purpose of left side figure. But I think this may be an 
incorrect comparison to motive the physics.

Slide5:
More fruitful process related to J/ψ in heavy-ion collisions: -> Leading 
J/psi production mechanisms in heavy-ion collisions:
Coalescence -> is this "co-mover"?

SLide6:
"J/ψ polarization at small pT,…" -> This discussion, in this slide, 
seems out of context. I would suggest remove this or make it clear how 
this is related with Modification of J/ψ feed-down. Or Am I 
misunderstood?

Slide13:
"Particle by Particle polarization of J/ψ in QGP" -> Not clear what is 
particle-by-particle?

Best
Nihar
