It is a general-purpose particle physics experiment run by an international collaboration and, same as <a href="https://cms.cern">CMS</a>, is designed to exploit the full discovery potential and the vast range of physics opportunities that the LHC provides.</p> <hr /> <p><a href="https://atlas.cern">ATLAS</a>' scientific exploration uses precision measurements to push the frontiers of knowledge by seeking answers to fundamental questions such as: What are the basic building blocks of matter? What are the fundamental forces of Nature? Could there be a greater underlying symmetry to our Universe?</p> <p>ATLAS physicists test the predictions of the <a href="https://home.cern/about/physics/standard-model">Standard Model</a>, which encapsulates our current understanding of what the building blocks of matter are and how they interact. These studies can lead to ground-breaking discoveries, such as that of the Higgs boson, physics beyond the Standard Model and the development of new theories to better describe our Universe.</p> <p>For more about the ATLAS Collaboration, the experiment, the physics and its members, please visit our <a href="https://atlas.cern/discover/experiment">Official Site</a>.</p> <h2 id="about-atlas-open-data">About <a href="http://opendata.atlas.cern">ATLAS Open Data</a></h2> <p><strong>The ATLAS Collaboration's current approach on the release of datasets is intended for Education, Training and Outreach activities around the World</strong>. In order to fulfil that objective, the <strong><a href="http://opendata.atlas.cern">ATLAS Open Data project</a> was created</strong>.</p> <p><a href="http://opendata.atlas.cern">ATLAS Open Data</a> project aims to provide data and tools to high-school, masters and undergraduate students, to help educate them in physics-analysis techniques used in experimental particle physics. Sharing data collected by the <a href="https://atlas.cern">ATLAS</a> experiment for educational purposes aims to generate excitement and enthusiasm for fundamental research, inspiring physicists of the future.</p> <p>The <a href="http://physicsmasterclasses.org/">International Masterclasses</a> introduce particle physics to high-school students and have been running very successfully for the last 20 years. ATLAS data <a href="https://www.interactions.org/press-release/high-school-students-analyse-first-time-real-lhc-data">were first used in 2011</a>, and 8 TeV ATLAS Open Data in 2015. Inspired by the success of International Masterclasses, a new <a href="http://opendata.atlas.cern">ATLAS Open Data</a> initiative <a href="https://atlas.cern/updates/atlas-news/explore-lhc-data-new-atlas-educational-platform">was launched in 2016</a>. And once again, a release in 2020, with a 10x more <a href="https://atlas.cern/updates/press-statement/13-tev-open-data">data recorded at 13 TeV centre-of-mass energy</a>.</p> <p>The target audience is physics undergraduate and masters students but may also include advanced high-school students or indeed anyone with some basic understanding of particle physics and coding experience.</p> <p>A comprehensive educational platform was developed featuring the 8 TeV and the more recent 13TeV dataset and a set of educational tools at a more advanced level. The objectives of this educative initiative are to provide:</p> <ul> <li>8 TeV proton–proton data collected by ATLAS plus associated simulated data.</li> <li>13 TeV proton–proton data collected by ATLAS plus associated simulated data.</li> <li>Tools and software of varying technical difficulty to analyse the data.</li> <li>An educational platform providing easy access to the data, software and tools with documentation in the form of step-by-step instructions for users.</li> </ul> <p>You can find usage instructions, examples, applications and suggestions in the dedicated ATLAS Open Data website <a href="http://opendata.atlas.cern">http://opendata.atlas.cern</a></p> <hr /> <p><strong>With the collaboration of the <a href="http://opendata.cern.ch">CERN Open Data</a></strong> team, we aim to publish, preserve and document real and simulated datasets, software and virtual machines, web and desktop applications, and up-to-date exercises and documentation, all for educational purposes.</p> <p>The ideal scenario is to have all the <a href="http://opendata.atlas.cern">ATLAS Open Data</a> resources replicated in both sites. We will do our best to reach this objective.</p> <h2 id="disclaimer"><a name="atlas-disclaimer">Disclaimer</a></h2> <ul> <li>The <a href="http://opendata.atlas.cern">ATLAS Open Data</a> are released under the <a href="http://creativecommons.org/publicdomain/zero/1.0/">Creative Commons CC0 waiver</a>.
