Experimental Dataset from BESIII detector at Beijing Electron-Positron Collider

摘要: In the BESIII detector at Beijing electron-positron collider, billions of events from e+e− collisions are recorded. These events passing through the trigger system are saved in raw data format files. They play an important role in the study of physics at τ -charm energy region. Here, we publish an e+e− collision dataset containing both Monte Carlo simulation samples and real data collected by the BESIII detector. The data passes through the detector trigger system, file format conversion, physics information extraction, and finally saves the physics information and detector response in text format files. This dataset is publicly available and is intended to provide interested scientists and those outside of the BESIII collaboration with event information from BE- SIII that can be used in understanding the physics research in e+e− collisions, developing visualization projects for physics education, public outreach, and science advocacy.
