pairs in different events. We determine the rescale of the mixed event denominator by considering the number of pairs of pairs for the case | Δ η | lying be- tween 1.2 and 1.5 plus any value of | Δ φ | for events and mixed events so that the overall ratio of this sample numerator to denominator is 1. By picking this Δ η bin for all | Δ φ | we have around the same pair count as the signal cut with the Δ φ correlation of the bubbles being washed out. For a simpler no- tation let (sign ( | Δ P $^{t}$1 | + | Δ P $^{t}$2 | )) = Δ P $^{t}$1 + Δ P $^{t}$2 which we plot in the range from -4 to +4 since we have an over all p t range 0.8 to 4.0 GeV/c. Thus the 

maximum magnitude of Δ P t ’s is 3.2 GeV/c which makes Δ P $^{t}$1 + Δ P $^{t}$2 have a range of ± 6.4. However the larger values near these range limits occur very rarely. 

In Fig. 18 we show the correlation function of op- posite sign charged-particle-pairs paired and binned by the variable Δ P $^{t}$1 + Δ P $^{t}$2 with a cut | Δ η | less than 0.2 between the vector sums of the two pairs, and with 40 ◦ < | Δ φ | < 48 ◦ . The events are gen- erated by the PBM[6] and are charged particles of 0.8 < p t < 4.0 GeV/c, with | η | < 1, from Au Au collisions at √ s NN = 200 GeV. Since we select pairs
