As part of its continued commitment to making its science fully open, the CMS collaboration has just publicly released, in electronic format, the combination of CMS measurements that contributed to establishing the discovery of the Higgs boson in 2012. This release coincides with the publication of the Combine software – the statistical analysis tool that CMS developed during the first run of the Large Hadron Collider (LHC) to search for the unique particle, which has since been adopted throughout the collaboration.

Physics measurements based on data from the LHC are usually reported as a


An expanded collaboration agreement between CERN and the OAPEN Foundation sees the Laboratory directly hosting the OAPEN Library and the Directory of Open Access Books in its Data Centre

CERN and the not-for-profit organization OAPEN Foundation are happy to announce a further expansion of their collaboration to jointly promote open access to books.

Since 2021, CERN and OAPEN (Open Access Publishing in European Networks) have collaborated to disseminate books that are made available in open access through SCOAP3 for Books, a collective open-access initiative hosted at CERN.

Building on this


The LHCb experiment at the Large Hadron Collider has released approximately 800 terabytes of data from Run 1, spanning 2011 and 2012. This pre-filtered data, aligned with CERN’s Open Data Policy, facilitates research and education in physics. With over 700 scientific publications and open-access papers, the released data allows access to the information behind significant findings. The collaboration has pre-processed the data, providing documentation, metadata, and a glossary for user understanding. The data is accessible on the CERN Open Data portal, complete with digital identifiers for


Eleven countries have introduced open science policies, strategies and legislative frameworks since the adoption of the UNESCO Recommendation on Open Science two years ago, according to the UNESCO Open Science Outlook 1: Status and Trends Around the World. This means that the total number of countries with open science policies has almost doubled. Other countries have adopted policies that pertain to one aspect of open science, such as for publications and/ or research data. The Outlook was launched on 14 December in Geneva at the European Organization for Nuclear Research (CERN) as a prelude


CERN launches its Open Source Program Office to help you with the release of your software and hardware designs

Sharing your work with collaborators in research and industry has many advantages, but it may also present some questions and challenges. To help you with all issues relating to the release of your software and hardware designs, we are launching CERN’s Open Source Program Office (OSPO).

In our community, it is common practice to publish open source software and hardware designs. By releasing your


In celebration of the 2023 Year of Open Science, CERN and NASA jointly organized “Accelerating the Adoption of Open Science”, a week-long open science summit at CERN in Geneva, Switzerland, from 10 to 14 July 2023. This event brought together a diverse range of attendees to exchange experiences, ideas, and expertise; promote open science policies and practices; and develop practical action plans to implement open science practices that are fit for both context and purpose. 

Through the course of the event, experts across the diverse domains of Open Science (i.e. open data, open software and


CERN and NASA join forces to commit to a research future that is open and accessible for all

This year, 2023, has been declared the Year of Open Science. This is why, for the first time, over 100 open science practitioners and policy-makers gathered at CERN’s Globe of Science and Innovation from 10 to 14 July. Co-organised by CERN, Europe’s leading particle physics laboratory, and NASA, the USA’s largest scientific agency, it brought together experts to discuss and learn how scientific bodies can promote and accelerate the adoption of open science. Over 70 different institutes were


Zenodo was launched 10 years ago on May 8th by CERN and OpenAIRE. The goal since day one has been to enable any researcher from anywhere in the world to participate in practising open science. Today, 10 years later, Zenodo supports more than 300,000 researchers in 7500+ research organisations in 153 countries to do just that. A recent study conservatively estimated the socio-economic impact of Zenodo in society to 95 million EUR per year but more likely close to 1 billion EUR/year. All in support of the mission to provide the platform for all researchers to publicly share their work and join


Today, the CERN Open Science Strategy Working Group has released the first version of the implementation plan that specifies concrete measures how to implement the CERN Open Science Policy, released on October 1st 2022. The implementation plan will be regularly updated to reflect organisational changes, updated priorities and new tools and practices. The most recent implementation plan will be also accessible on this website.


On March 24th, International Committee of the Red Cross (ICRC) representatives from its Delegation for Cyberspace came to CERN for the first in a series of knowledge-sharing sessions on using free and open source technologies to support the vital humanitarian work they carry out across the globe. These technologies are being explored as a means to pursue neutrality, impartiality and independence of humanitarian action in a digital environment. CERN and the ICRC have signed a cooperation agreement that will see members of CERN’s IT department provide training on selected technologies, as well


Ever since the open access (OA) publication of peer-reviewed primary research articles from CERN authors was made a policy requirement in 2014, CERN has made great strides forward in opening its research to anyone around the world. This has been achieved thanks to a variety of mechanisms implemented by the CERN Scientific Information Service (SIS), ranging from a series of Read & Publish agreements signed with major publishers to CERN’s participation in the SCOAP3 consortium, which has arranged for automatic OA to research in high-energy physics (HEP).

Books (including monographs and


The Large Hadron Collider Beauty (LHCb) experiment at CERN is the world’s leading experiment in quark flavour physics with a broad particle physics programme. Its data from Runs 1 and 2 of the Large Hadron Collider (LHC) has so far been used for over 600 scientific publications, including a number of significant discoveries. While all scientific results from the LHCb collaboration are already publicly available through open access papers, the data used by the researchers to produce these results is now accessible to anyone in the world through the CERN open data portal. The data release is


All proton-proton data collected by the CMS experiment during LHC Run-1 (2010-2012) are now available through the CERN Open Data Portal. Today’s release of 491 TB of collision data collected during 2012 culminates the process that started in 2014 with the very first release of research-grade open data in experimental particle physics. Completing the delivery of Run-1 data within 10 years after data taking reaffirms the CMS collaboration’s commitment to its open data policy.

The newly released data consist of 42 collision datasets from CMS data taken in early and late 2012 and count an


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 of transparency and collaboration at CERN

During its 209th Council session in September, the CERN Council approved a new policy for open science at the Organization, with immediate effect. The policy aims to make all CERN research fully accessible, inclusive, democratic, and transparent, both for other researchers and the wider society. It was developed by the Open Science Strategy Working Group (OSSWG), which encompasses


The Sponsoring Consortium for Open Access Publishing in Particle Physics (SCOAP3)—the world’s largest disciplinary open access initiative—has reached the milestone of over 50’000 research articles published. Through partnerships with 11 leading journals, SCOAP3 has effectively transitioned the vast majority of research articles in the discipline to perpetual OA since 2014. These research papers include vital contributions from research organizations and institutions across the world: including the last paper published by Stephen Hawking and colleagues on Black Hole Entropy and a seminal paper


As the experiments at the Large Hadron Collider (LHC) brace for the start of Run 3 of the accelerator’s programme in 2022, the CMS collaboration has released a new batch of research-quality open data recorded by the CMS detector in 2015, the first year of Run 2. The new datasets are now available on the CERN Open Data portal. This marks the seventh release of CMS open data since 2014. It is the first release of research-quality open data from the LHC recorded at 13 teraelectronvolts (TeV), the record-breaking collision energy at which the accelerator operated during Run 2.

Data from hundreds


We’ve talked in the past about the challenges of running a service at the scale of Zenodo in the inhospitable environment of the modern internet. Over the past couple of years, we have experienced an exponential increase in our users, content, and traffic… and we couldn’t be happier that Zenodo is proving useful in so many different ways! For Open Science to flourish, researchers should feel empowered to share their data, software, and every part of their journey of publishing their work. We are proud to have done our part in lowering the barrier to share and preserve.

This year we crossed


The four main LHC collaborations (ALICE, ATLAS, CMS and LHCb) have unanimously endorsed a new open data policy for scientific experiments at the Large Hadron Collider (LHC), which was presented to the CERN Council today.  The policy commits to publicly releasing so-called level 3 scientific data, the type required to make scientific studies, collected by the LHC experiments. Data will start to be released approximately five years after collection, and the aim is for the full dataset to be publicly available by the close of the experiment concerned. The policy addresses the growing movement of


The ATLAS collaboration has just released the first open dataset from the Large Hadron Collider’s (LHC) highest-energy run at 13 teraelectronvolts (TeV). The new release is specially developed for science education, underlining the collaboration’s long-standing commitment to students and teachers using open-access ATLAS data and related tools.

ATLAS has made public 10 inverse femtobarns (fb−1) of the 13-TeV data, which corresponds to about 1 quadrillion proton-proton collisions, or 500 thousand produced Higgs bosons. It is also approximately the same amount of data that the ATLAS
