Rare particle decay could mean new physics

(PhysOrg.com) -- An incredibly rare sub-atomic particle decay might not be quite as rare as previously predicted, say Cornell researchers. This discovery, culled from a vast data set at the Collider Detector at Fermilab (CDF), ...

Putting quarks on a virtual scale

For the last several years, much of the attention in particle physics has focused on the Higgs Boson, so one could be forgiven thinking that the rest of the subatomic particle world has been figured out. ...

The debut of the antihydrogen beam

The standard model of particle physics suggests that matter and antimatter are equal and opposite in every way. Yet the observable Universe is made almost entirely of matter—an asymmetry that remains one ...
