Comparison of angular distributions of prompt/displaced background

These show the comparison between prompt and displaced distributions of cosθ and φ in the Collins-Soper frame. The histogram is the prompt component and the error bars are the displaced component. The figures show that there is agreement both at low mass, below the ϒ(1S), and at high mass, above the ϒ(3S) signals in both the CMUP+CMU and CMUP+CMX trigger samples.
