CERN’s core values include making research open and accessible for everyone. A new policy now brings together existing open science initiatives to ensure a bright future based on transparency and collaboration at CERN.

CMS data recorded in 2010 and 2011 from lead–lead collisions at the Large Hadron Collider have been released into the public domain for the first time

A new open data policy for scientific experiments at the Large Hadron Collider (LHC) will make scientific research more reproducible, accessible, and collaborative

All research-quality data from proton–proton collisions recorded by CMS during the first two years of LHC operation are now publicly available

Zenodo and OpenAIRE are contributing to the European Commission call for action with what they do best – preserving and sharing all COVID-19-related datasets, software, preprints and other research objects

The collaboration has made public the data of 1 quadrillion proton-proton collisions from the LHC’s last run

CMS has also provided open access to 100% of its research data recorded in proton–proton collisions in 2010

As well as making data from particle physics research public, the CMS experiment has developed additional tools in github to be used in schools

This release includes datasets that were used to discover the Higgs boson

In October 2017 the CERN data centre broke its own record for data storage when it collected 12.3 petabytes of data over a single month

The Technical University of Dortmund (Germany) is the first university to use ATLAS data in a lab course

The ATLAS experiment at CERN released data from 100 trillion proton-proton collisions in the LHC in 2012
