Large Hadron Collider is on again
DOI: 10.1063/PT.5.028769
Nature: CERN’s Large Hadron Collider (LHC) has finally restarted after a two-year shutdown to upgrade the facility for higher intensities and collision energies. The LHC was supposed to be activated two weeks ago, but a short circuit delayed operations. Two beams of protons are currently circling through the 27-km main ring of the collider—it will be weeks before the first collisions are initiated. In the meantime, the beam energy will increase from 450 GeV to 6.5 TeV. Once collisions start they will have energies of around 13 TeV, up from the previous 8 TeV. That boost in energy could potentially be high enough to reveal new physics beyond the standard model of particle physics.
