STAR HardProbes PWG

[zli1 <zli1 AT rcf.rhic.bnl.gov>]

Hi Nihar,

Thanks for your question.

The issue you've noticed arises because the yield values of dimuon Y(2S) 
are negative in the mentioned bins (Cen010 and pT5_10). The 
corresponding Y(2S) R_AA values from the dimuon channel are also 
negative.

However, we didn't present these R_AA values (from either the dimuon or 
dielectron channel) in the slides or the paper. The R_AA values shown 
are the combined results, which are indeed positive.

I hope this clears up any confusion, and I'm happy to provide further 
explanation if needed.

Best,
Ziyang
