Dear Baoshan,

Thanks for the updated abstract. I have additional suggestions below for your consideration.

"Global spin alignment can provide valuable insights into the Chiral Magnetic Effect in relativistic heavy ion collisions."
--> How about starting it as: The search for the Chiral Magnetic Effect (CME) is ongoing in relativistic heavy-ion experiments. It is crucial to scrutinize the CME-sensitive observables to rule out non-CME contributions.

"STAR has measured the global spin alignment for φ and k∗0 meson, where φ meson exhibits a clear signal. While the global spin alignment for φ meson is argued to be sensitive
to the local fluctuations of the strong force field"
--> How about rephrasing it: Recently STAR has measured an unexpectedly large signal of global spin alignment (\rho_00) for φ meson, which is argued to be sensitive to the local fluctuations of the vector meson strong force field [1].

"the global spin alignment of vector mesons can influence CME-sensitive observables[2,3]. The finite global spin alignment of vector mesons, particularly the ρ0 meson, can either positively or negatively resemble the CME signal, depending on the sign of (ρ00 - 1/3)."
--> How about: A finite \rho_00 of vector mesons can influence CME-sensitive observables. In particular, the ρ00 of ρ mesons can induce a positive (negative) contribution to the CME observables, depending on the deviation of ρ00 being larger (smaller) than 1/3 [2,3].

I would suggest to remove the sentence "It is critical to understand to .... interpretation of CME observables". It sounds redundant.

"In this talk, we present STAR’s measurements of the global spin alignment for rho meson in Au+Au and Isobar (Zr+Zr and Ru+Ru) collisions at 200 GeV,..."
--> In this talk, we will present measurements of the global spin alignment for $\rho$ meson as functions of transverse momentum and centrality in Au+Au and Isobar (Zr+Zr and Ru+Ru) collisions at \sqrt{s_{NN}} = 200 GeV.

"We will also discuss the implications of our results on CME search."
--> We will discuss the implications of our results in the context of interpreting CME observables.

Thanks and regards,
Subhash

Dear Subhash

Thanks for the helpful comments. I have updated the abstract in the same link.

Regards,
