Experimental dataset from BESIII detector at Beijing electron positron collider
In the BESIII detector at Beijing electron positron collider, billions of events from $e^+e^-$ collisions were recorded. These events passing through the trigger system were saved in raw data format files. They play an important role in the study of physics in tau-charm energy region. Here, we published an $e^+e^-$ collision dataset containing both Monte Carlo simulation samples and real data collected by the BESIII detector. The data pass through the detector trigger system, file format conversion, and physics information extraction and finally save 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 BESIII, which can be used to understand physics research in $e^+e^-$-collisions, developing visualization projects for physics education, public outreach, and science advocacy.
