  CMS has recently conducted the largest deletion campaign in its history, deleting roughly 85 Petabytes (85’000’000’000’000’000 bytes) of data from the magnetic tapes, in order to free up space for the Run 3 collisions. No original raw data have…

  In 2012, the ATLAS and CMS Collaborations observed a new boson with a mass of 125 GeV, whose properties are compatible with those of the Higgs boson predicted by the Standard Model (SM) of particle physics. However, numerous models beyond the SM (…
