The LHC's peta-bytes

As the LHC generates each second billions of billions of collisions between protons, each of these collisions generates about a megabyte of data. The author first recalls the different detectors which record traces of collisions, outlines that the Higgs boson is rarely produced by these collisions, and moreover, disintegrates into two Z bosons. This means that the detection rate is very low. She outlines the huge number of data generated by each experiment, and evokes how they are processed, and outlines the associated required computing capacities
