Slides summarizing cuts, procedure, and final results:
Same Event (black), Mixed Event (red), and Same - Mixed Event (blue) in cos(θ*) bins and smaller pT bins:
STAR/system/files/userfiles/6551/InvMassDistributions_27GeV_Order2_Cent9.pdf
We then sum the Same - Mixed Event histograms into larger pT bins. We fit the invariant mass distribution with a Breit-Wigner + poly1 function and extract ρ00.
Invariant mass distributions for cos(θ*) bins and larger pT bins. Fit for ρ00 extraction is also shown:
