Simulated background dataset for Generator Based Inference (GBI) study

This is the generated background dataset used in the Generator Based Inference (GBI) study. The original backgroud data comes from LHCO dataset (https://zenodo.org/records/4536624). A conditional flow matching model is used to learn the background distribution in the side band region and interpolate it into signal region, then it generates 366570 background samples in the signal region.
