Kinematic distributions for negative, positive tracks and track pairs, decAngle is the decay angle in the center of mass frame, opening angle the distance between the tracks in eta-phi space (note the cut at 0.3 in the analysis)

Eta:

azimuthal angle of R to scattering plane, S and azimuthal angle between R and S (phi_{RS})

DCA of tracks (before any of the other cuts) in cm:
