STAR GPC #355

[Yu Hu <yuhu AT lbl.gov>]

Hi Yicheng,

Thank you very much, equation 23, 25, and 26 helped me a lot on this.

Do you think it helps to add e.q 23 to your long paper? Or do you think this one is a small detail and might not need? 

Best,

Yu

Hi Yu,

Thank you for your comments. 

There are some related algebra details in the analysis note:

https://drupal.star.bnl.gov/STAR/system/files/IsobarNfBkg_Note_v5.pdf

Eqs.23-27 in pages 30-31 should be helpful to answer your questions.

If you have any further questions or comments, please let me know.

Sincerely,

Yicheng

Hi Yicheng, Jamie, and All,

I rethink what I said this morning, I think the question I had is because I didn't fully understand equation 21 in the long paper, that's why I was asking maybe directly show the (Y - Ybkg)/Ybkg. But I'm also ok with what Yicheng shows here in the short paper fig 4 (and long paper fig 14), it is actually a step forward using the B difference to get individual (Ru+Ru system or Zr+Zr system) f_cme. But Yicheng, can you explain to me how you get from the left side to your right side in equation 21? Sorry, I don't have a direct connection between f_cme (Ru) and the measured double ratio of the two systems in my mind. :)

Thank you.

Best,

Yu
