Scientists report the discovery of antimatter particles held by the Earth's magnetic field, created by collisions of high-energy cosmic rays with particles from the upper atmosphere.
Scientists have observed a new particle, the neutral Xi-sub-b.While its existence was predicted by the Standard Model, the observation of the neutral Xi-sub-b is significant because it strengthens our understanding of how quarks form matter.
New constraints on the elusive Higgs particle are more stringent than ever before. Scientists of the CDF and DZero collider experiments revealed their latest Higgs search results today. Their results rule out a significant fraction of the allowed mass range established by earlier experiments.
The world's largest particle accelerator (LHC) has yielded its first measurements of fundamental subatomic particles, so far confirming physicists' Standard Model but also paving the way to future discoveries that may offer new insights into the forces that govern the universe.
The possibility of the Large Hadron Collider destroying the Earth could yet be debated in court. If the right kind of claim is filed in the proper court, a judge may soon have to face the question of whether an injunction might be needed to save the world.
