The BES collaboration at the Beijing Electron Positron Collider (BEPC) has observed a clear signal for a narrow enhancement in the ppbar mass distribution near the 2mp threshold in the process J/Ψ→...
Read article 'Has the deconfinement phase transition been seen?'
New results from the NA49 experiment at CERN suggest that the onset of the transition to deconfined quarks and gluons has been observed at the lower end of the SPS energy region.
