Background information:
https://en.wikipedia.org/wiki/CERN
The term CERN is also used to refer to the laboratory, which in 2016 had 2,500 scientific, technical, and administrative staff members, and hosted about 12,000 users. In the same year, CERN generated 49 petabytes of data.[6]
CERN's main function is to provide the particle accelerators and other infrastructure needed for high-energy physics research – as a result, numerous experiments have been constructed at CERN through international collaborations. The main site at Meyrin hosts a large computing facility, which is primarily used to store and analyse data from experiments, as well as simulate events. Researchers need remote access to these facilities, so the lab has historically been a major wide area network hub. CERN is also the birthplace of the World Wide Web.
Several important achievements in particle physics have been made through experiments at CERN. They include:
- 1973: The discovery of neutral currents in the Gargamelle bubble chamber;
- 1983: The discovery of W and Z bosons in the UA1 and UA2 experiments;
- 1989: The determination of the number of light neutrino families at the Large Electron–Positron Collider (LEP) operating on the Z boson peak;
- 1995: The first creation of antihydrogen atoms in the PS210 experiment;
- 1999: The discovery of direct CP violation in the NA48 experiment;
- 2010: The isolation of 38 atoms of antihydrogen;[13]
- 2011: Maintaining antihydrogen for over 15 minutes;CERN
- 2012: A boson with mass around 125 GeV/c2 consistent with the long-sought Higgs boson

CERN news : ALPHA2 ANTIMATTER
Geneva, 7 March 2012. In a paper published online today by the journal Nature, the ALPHA collaboration at CERN* reports an important milestone on the way to measuring the properties of antimatter atoms. This follows news reported in June last year that the collaboration had routinely trapped antihydrogen atoms for long periods of time. ALPHA's latest advance is the next important milestone on the way to being able to make precision comparisons between atoms of ordinary matter and atoms of antimatter, thereby helping to unravel one of the deepest mysteries in particle physics and perhaps understanding why a Universe of matter exists at all.

Sonified Higgs data show a surprising result
By analyzing the data from collisions in the LHC experiments using music to translate what they see, scientists have been able to make out faint patterns of music that sound like well known tunes...

The ALPHA experiment observes light spectrum of antimatter for the first time
ALPHA is an antimatter experiment set up in late 2005. ALPHA makes, captures and studies atoms of antihydrogen and compares these with hydrogen atoms.
In a paper published today in the journal Nature, the ALPHA collaboration reports the first ever measurement on the optical spectrum of an antimatter atom. This achievement features technological developments that open up a completely new era in high-precision antimatter research. It is the result of over 20 years of work by the CERN antimatter community.
