Hi Ziyang,

   Thanks for implementing the suggestions. I dont have further comments and sign off

thanks

Hello Sooraj and Yi,

Thanks for your useful comments, I upload a new version v2 on drupal.

Based on Sooraj's comments, in addition to the modified text,
I rewrite sec 2
I adjust the order of figures and corresponding discussions in sec 3.2,
now they follow pT,pT^2, and mass distribution.

Based on Yi's comments, in addition to the modified text,
I think dielectron is better, thank you! And I changed dimuon to mu+
mu-, except in the title and dimuon trigger.
  - L31: In this proceeding   Sorry, I didn't catch your meaning.
L76, since I adjust the order, so the references are still in the same
position.

Best,
Ziyang
