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), ...

Fermilab experiment discovers a heavy relative of the neutron

(PhysOrg.com) -- Scientists of the CDF collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced the observation of a new particle, the neutral Xi-sub-b (Ξb0). This particle contains ...

Particle oddball surprises physicists

(PhysOrg.com) -- Scientists of the CDF experiment at the Department of Energy's Fermi National Accelerator Laboratory announced yesterday that they have found evidence of an unexpected particle whose curious characteristics ...

Fermilab experiment fails to confirm new particle claim

(PhysOrg.com) -- In April, scientists at one of Fermilab’s two particle detectors, CDF, observed what they thought might be a new particle not predicted by the Standard Model. But now, scientists at the lab’s second ...

Scientists complete the top quark puzzle

Scientists on the CDF and DZero experiments at the U.S. Department of Energy's Fermi National Accelerator Laboratory have announced that they have found the final predicted way of creating a top quark, completing a picture ...

Experiment confirms existence of odd particle

Scientists working on the CMS experiment at the Large Hadron Collider have confirmed the existence of an odd, puzzling particle first observed a few years ago at DOE's Tevatron particle collider. Members of the CMS collaboration ...

Researchers observe new unexplained particle states

In the vast particle landscape, there are, to borrow a phrase, known knowns (the Standard Model, for example), unknown unknowns (exotic extensions of the Standard Model and beyond), and those ever-interesting known unknowns. ...
