About

This dataset contains 100,000 particle collision events involving two electrons, specifically dielectron events. The data is provided within an invariant mass range of 2-110 GeV. It was specifically curated for outreach and education purposes and represents a subset of the total event information. It is important to note that the selection criteria used for this dataset may differ from those employed in official CMS physics results.

Distribution

The dataset is provided in a CSV file named dielectron.csv. It contains 100,000 dielectron events, and consists of 19 columns. The file size is 14.74 MB. For the invariant mass (M), there are 99,900 valid entries. This dataset is not expected to be updated.

Usage

This dataset is ideal for educational purposes in physics and data science. It can be used for teaching and learning about particle collision analysis, invariant mass calculations, and fundamental concepts in high-energy physics. It is also suitable for data analytics exercises and scientific outreach programmes.

Coverage

The data consists of particle collision events recorded at CERN. The run numbers provided offer insight into the time range of data collection, such as runs from 146511.00 to 149182.00. This dataset originates from the CMS experiment at CERN and focuses on physics phenomena rather than having a traditional geographic or demographic scope.
