Hello Tristan,

Please find my following suggestions.

L11: "…observables, including dihadron correlations and dijet 
asymmetry." -> "…observables, such as dihadron correlations, dijet 
asymmetry, etc.

"Another approach to  measure jet quenching effects is to determine the 
anisotropy of the distribution of jets with respect to the event plane."
I would suggest to modify your sentence like
"Nevertheless, the path length dependence of jet quenching can be 
studied by measuring the anisotropy of the jet distributions with 
respect to the event plane in heavy-ion collisions."
Then your next sentence "Due to the approximately elliptical …" comes 
coherently in a flow.

L16: v_{2}^{ch jet} -> v_{2}^{jet}  [you don't need to mention "ch jet" 
as you have mentioned using "charged jet" in that sentence, this is 
fine]

L17: "Zr+Zr systems."-> "Zr+Zr collision systems."

L19-21:"The EPD enables this measurement by allowing the event plane to 
be determined in the forward region, creating a gap in rapidity from 
where jets are found which  reduces autocorrelation effects with respect 
to the event plane determination."
-> I would rephrase this.  "The EPD enables the determination of the 
event plane in the forward rapidity, whereas jets are measured at the 
mid-rapidity that mitigates the autocorrelation to the jet measurement 
in STAR."

cheers
Nihar
