Hi Tristan,

Nice abstract. I have minor suggestions for your consideration and sign off.

L1:  in Heavy Ion Collisions at STAR ->  in Isobar Collisions at sqrt{s_NN} = 200 GeV in STAR

L12: the anisotropy of the distribution -> the anisotropy of the transverse momentum distribution

L20: at forward rapidity -> you can add: with good resolution

Cheers,

Barbara
