STAR Flow, Chirality and Vorticity PWG

Hi Jiangyong,

1) For the spectra I agree we need to follow up later on it. I general my results 1/pT dN/dpT but in PRL it was 1/pT d2N/dpTd\eta. I will work more on that.

2) You can find dphi plot attached.

Cheers,
Niseem

Hi, Niseem,

Thanks for these plots.

1) your the pT spectra is about x2 higher at 10 GeV. Are you plotting 1/pT dN/dpT or just dN/dpT (both your and PRL)?

This difference probably implies an effect of momentum resolution at high pT, which also probably implies your statistics is x2 too large due to this effect. What it does is it make your v2 error bar appears smaller than it should be.  This need to be followed up later.

2) the dphi plots looks nice. Could you overlay them with 10-20% central data?

cheers,

Jiangyong

        Please find attached the spectra comparisons for 10-20%
        centrality. This, not a final comparison since I need to run
        with the same cuts as in the STAR publications. 
        Also, you can find attached the dPhi-plot attached for different
        high pt region for 90% centrality. 
        
        
        Thanks,
