What is Cern: Definition and 152 Discussions

The European Organization for Nuclear Research (French: Organisation européenne pour la recherche nucléaire), known as CERN (; French pronunciation: [sɛʁn]; derived from the name Conseil européen pour la recherche nucléaire), is a European research organization that operates the largest particle physics laboratory in the world. Established in 1954, the organization is based in a northwest suburb of Geneva on the Franco–Swiss border and has 23 member states. Israel is the only non-European country granted full membership. CERN is an official United Nations Observer.The acronym CERN is also used to refer to the laboratory, which in 2019 had 2,660 scientific, technical, and administrative staff members, and hosted about 12,400 users from institutions in more than 70 countries. In 2016 CERN generated 49 petabytes of data.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. CERN is the site of the Large Hadron Collider (LHC), the world's largest and highest-energy particle collider. 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.

    What are the best high-energy physics establishments?

    I am thinking of places to do summer work placements in the high-energy physics field between each year of my degree. I have thought of CERN (of course) and Fermilab as the two definites. However I am struggling to think of a third. Also, I would prefer Europe/US so this rules out T2K. Any...

    Energy & Time Dilation in Large Hadron Collider (LHC)

    Due to the blogs being removed, I thought it might be worthwhile posting a few in the forums-The Large Hadron Collider has produced collisions at 7 TeV. For collisions at 7 TeV, protons need to be ‘ramped’ to 3.5 TeV, the proton has a mass of 1.6726e−27 kg which, according to mass–energy...

    What is the meaning of this String Theory Equation from CERN?

    Unveiling the Mystery of Proton Spin

In that case, 3 spin 1/2 particles can't be added...
