Data Preservation at LEP

TL;DR

This paper reviews the efforts and current status of data preservation for the LEP experiments ALEPH, DELPHI, L3, and OPAL, emphasizing the importance of safeguarding unique high-energy physics data for future research.

Contribution

It provides a comprehensive overview of the data preservation initiatives and tools developed by the LEP experiments after data collection ended.

Findings

Data from LEP experiments is unique and cannot be repeated.

Preservation efforts include developing tools and maintaining data accessibility.

Current status shows ongoing management and potential for future analysis.

Abstract

The four LEP experiments ALEPH, DELPHI, L3 and OPAL successfully recorded e+e- collision data during the years 1989 to 2000. As part of the ordinary evolution in High Energy Physics, these experiments can not be repeated and their data is therefore unique. This article briefly reviews the data preservation efforts undertaken by the four experiments beyond the end of data taking. The current status of the preserved data and associated tools is summarised.
