Brown physicists play key role in single top quark discovery
Brown University physicists have played a key role in observing particle collisions that produce a single top quark, one of the fundamental constituents of matter. The discovery was announced Monday by scientists of the CDF and DZero collaborations at the Department of Energy's Fermi National Accelerator Laboratory. view more (2009-03-10)
UCR-led research team detects 'top quark,' a basic constituent of matter
A group of 50 international physicists, led by UC Riverside's Ann Heinson, has detected for the first time a subatomic particle, the top quark, produced without the simultaneous production of its antimatter partner - an extremely rare event. view more (2006-12-14)
Research team co-led by UC Riverside physicist observes production of single-top-quarks
A group of 28 scientists at the U.S. Department of Energy's Fermi National Accelerator Laboratory, co-led by UC Riverside's Ann Heinson, has made the first observation of the production of single top quarks - an observation that resulted from proton-antiproton collisions measured by the DZero detector in Fermilab's Tevatron, the world's... view more...

DZero finds evidence of rare single top quark; Observation marks a step closer to finding Higgs boson
Scientists of the DZero collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced in a seminar at Fermilab on December 8, 2006 the first evidence of single top quarks produced in a rare subatomic process involving the weak nuclear force. view more (2006-12-18)
Undergraduate Helps Discover Beautiful Quark Combinations
University of Rochester physics undergraduate Scott Field participated in the search for two subatomic particles whose existence was announced today by scientists at the Fermi National Accelerator Laboratory (Fermilab) in Illinois. Field's research focused on the extremely rare quark of the "bottom" or "beauty" variety. view more (2006-10-24)
What Happened to the Antimatter? Fermilab's DZero Experiment Finds Clues in Quick-Change Meson
Scientists of the DZero collider detector collaboration at the Department of Energy's Fermi National Accelerator Laboratory have announced that their data on the properties of a subatomic particle, the B_s meson ("B sub s"), suggest that the particle oscillates between matter and antimatter in one of nature's fastest rapid-fire... view more...

Particle oddball surprises CDF physicists at Fermilab
Scientists of the CDF experiment at the Department of Energy's Fermi National Accelerator Laboratory announced yesterday (March 17) that they have found evidence of an unexpected particle whose curious characteristics may reveal new ways that quarks can combine to form matter. view more (2009-03-19)
Moving Quarks Help Solve Proton Spin Puzzle
New theory work at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility has shown that more than half of the spin of the proton is the result of the movement of its building blocks: quarks. view more (2008-09-15)
CDF precision measurement of W-boson mass suggests a lighter Higgs particle
Scientists of the CDF collaboration at the Department of Energy's Fermi National Accelerator Laboratory announced today (January 8, 2007) the world's most precise measurement by a single experiment of the mass of the W boson, the carrier of the weak nuclear force and a key parameter of the Standard Model of particles and forces. The new W-mass... view more... (2007-01-09)
JHU-led team discovers exotic relatives of protons and neutrons
A team of scientists, including four at The Johns Hopkins University, has discovered two new subatomic particles, rare but important relatives of the familiar, commonplace proton and neutron. view more (2006-11-17)
Precision measurement of W boson mass portends stricter limits for Higgs particle
Scientists of the DZero collaboration at the Department of Energy's Fermi National Accelerator Laboratory have achieved the world's most precise measurement of the mass of the W boson by a single experiment. Combined with other measurements, the reduced uncertainty of the W boson mass will lead to stricter bounds on the mass of the elusive Higgs... view more... (2009-03-12)
Physicist: Stars can be strange
According to the "Strange Matter Hypothesis," which gained popularity in the paranormal 1980's, nuclear matter, too, can be strange. view more (2006-12-19)
G-Zero Finds that Ghostly Strange Quarks Influence Proton Structure
In research performed at the Department of Energy's Jefferson Lab, nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton's quark-gluon sea contribute to a proton's properties. view more (2005-06-20)
G-Zero update
In research performed in Hall C, nuclear physicists have found that strange quarks do contribute to the structure of the proton. This result indicates that, just as previous experiments have hinted, strange quarks in the proton's quark-gluon sea contribute to a proton's properties. The result comes from work performed by the G-Zero collaboration,... view more... (2006-06-30)
Proton's party pals may alter its internal structure
A recent experiment at the Department of Energy's Thomas Jefferson National Accelerator Facility has found that a proton's nearest neighbors in the nucleus of the atom may modify the proton's internal structure. view more (2009-11-19)
U-M physicists' analysis leads to discovery of new particle
