Experiments at the CERN SPS: first signals of deconfinement
Abstract
Heavy-ion experiments at the CERN SPS began in the mid-1980s to study nuclear matter at extreme temperatures and densities. The program started with light ions, such as oxygen and sulphur, at energies of 60A GeV and 200A GeV, later advancing to lead ions at 158A GeV. A series of experiments, employing novel detector technologies, explored various signatures of quark-gluon plasma (QGP) formation. In February 2000, these results led CERN to announce evidence for the QGP formation. Subsequently, an energy scan was conducted with lead ions from 20A GeV to 158A GeV, to locate the threshold of QGP creation.
