Experimental Dataset from BESIII detector in Beijing Electron-Positron Collider

In the BESIII detector at Beijing electron-positron collider, billions of events from collisions are recorded.These events passing through the trigger system are saved in raw data format files. They play an important role in the physics study of the τ-charm area. Here, we introduce an electron-positron collision dataset containing both the simulated samples and the actual data collected by the BESIII detector, which passes through the detector trigger system, file 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 community with event information from BESIII that can be used in understanding the physics research in electron-positron collisions, developing visualization projects for physics education, public outreach, and science advocacy.
