The CMS experiment ( Compact Muon Solenoid ) CERN (European Laboratory for Particle Physics) released on Friday half of the data collected in 2011: 300 terabytes data. To get an idea of what this is, remember that the hard disk of a modern computer is generally a terabyte of capacity to store information.
This is the second time that the collaboration CMS makes public data from LHC collisions ( Large Hadron Collider ), the largest accelerator CERN particle, recorded at the detector. In November 2014, had provided 27 terabytes of data collected in 2010, revealed the site this team.
The data are available at CERN Open Data Portal platform in order to be able be used by anyone – either with an educational purpose, either for research – as long as the data source is properly attributed. This platform is also intended to provide data from other experiments (and detectors) of the LHC, as ATLAS, ALICE and LHCb
The group of CMS researchers released two types of data collection:. Raw data such as those commonly analyzed, and data processed, which require less computation effort. But CMS also provided protocols for simulation data, such as those that need to use during the research work they do, and also a software that data visualization (as in the video above).
“the members of the collaboration CMS put a lot of effort and thousands of person-hours of service so as to operate the CMS detector and to collect this data for analysis,” said Kati Lassila-Perini, physics responsible for the preservation effort data. “However, once we have explored the most of the data, we see no reason for not disponibilizarmos publicly. The benefits are numerous, since inspire high school students to the training of physical particles of tomorrow. And personally as coordinator of preserving the CMS data, this is a crucial part to ensure that the research data will be available in the long term. “
The experience of making public data has shown can bear fruit . After the 2010 data were made public in 2014, a group of theoretical physicists at MIT (Massachusetts Institute of Technology) made a proposal for an analysis of the data that the CMS collaboration had not explored. And so it established a partnership between the two research groups.
“As scientists, we must take this issue of release of data financed by public money very seriously,” said Salvatore Rappoccio, a physical CMS that collaborated directly with the MIT team. “In addition to showing a good administration of the funds received, also it provides a scientific benefit to our area as a whole. Although it is a difficult and daunting task still much to do, the disclosure of CMS data is a giant step in the right direction. “
