Good news for physicists and other researchers around the world, since CERN has published, for free online access, more than 300 TB of high-quality data on collisions recorded in recent years. This is not the first time, only the largest publication had been 27TB in 2014.
The data is found on the opendata.cern.chy portal and is published, under a Creative Commons license (CC0 1.0, that is, you can do almost anything with it), by the team of the Compact Muon Solenoid (CMS) who works in one of the two major projects of the LHC or Large Hadron Collider located between France and Switzerland.
The data set includes primary datasets and secondary datasets, the latter being the ones that will best come to Universities and other academic institutions, since they may be treated with less computing power. In any case, there will be code examples (for simulations, especially) and additional tools also for such advanced handling and analysis including a virtual machine image called CernVM.
The idea of the launch is to promote the preservation of such valuable information for a long time and that could be useful to a large number of researchers, what happened with the 2014 publication that for example caught the attention of a group of MIT scientists ( jet properties) and German students (visualization of collisions) who are already working taking advantage of what is publicly provided by CERN.
