  author={Kati Lassila-Perini and Clemens Lange and Edgar Carrera Jarrin and Matthew Bellis},
The CMS experiment at CERN has released research-quality data from particle collisions at the LHC since 2014. Almost all data from the first LHC run in 2010–2012 with the corresponding simulated samples are now in the public domain, and several scientific studies have been performed using these data. This paper summarizes the available data and tools, reviews the challenges in using them in research, and discusses measures to improve their usability.

Exploring Uncharted Soft Displaced Vertices in Open Data
A cluster of soft displaced tracks corresponds to the dark matter co-annihilation regime. The longlived regime is, in particular, motivated by the unexplored top partner physics. The background inExpand
