Do particles and their antiparticles behave in the same way? Even tiny differences could be amplified over astronomical distances to produce very large effects.
New data from the KTeV experiment at Fermilab blow away some of the fog around the mystery of CP violation and underline the effects suggested by earlier results from CERN.
The CDF experiment at Fermilab's Tevatron protonantiproton collider has produced heroic new evidence for the violation of "CP" symmetry, a hypothetical operation which takes a particle into a mirro...
New results remind us how, in the strange world of the neutral kaon, a fast rewind does not necessarily take you back to where you started.
The LHCb experiment has been formally approved for CERN's LHC collider.
With CERN's site straddling the FrancoSwiss frontier near Geneva, exporting particle beams is an everyday occurrence. Now a new proposal foresees CERN particles also being exported to Italy, for u...
New evidence from CERN's Large ElectronPositron collider (LEP) sheds more light on the way quarks can transform.
