comparison of the phi meson spectra measured by STAR and PHENIX

Updated on Thu, 2010-09-30 09:28. Originally created by mnaglis on 2010-09-07 10:52.

This comparison is restricted to 200 GeV data only, KK decay channel only.

STAR data points are from:
Phys. Rev., 2009, C79, 064903 - p+p, d+Au, Au+Au
Phys.Lett.B673:183-191,2009 - Cu+Cu

PHENIX data points are from:
arXiv.org:1004.3532v2/nucl-ex - p+p, d+Au, Au+Au, Cu+Cu

Solid symbols correspond to same centrality bin used by STAR and PHENIX. Open symbols used when centrality bins are different.
Solid blue and solid red points should be compared.

 

Au+Au

Since I used fit to PHENXI data point to make ratios, comparison is fair onlly above pt=1.1 GeV/c.
