DZero

New constraints on the elusive Higgs particle are more stringent than ever before.

Scientists of the DZero collaboration at the Department of Energy’s Fermi National Accelerator Laboratory announced Friday, May 14, that they have found evidence for significant violation of matter-antimatter symmetry in the behavior of particles containing bottom quarks beyond what is expected in the current theory, the Standard Model of particle physics.

The territory where the Higgs boson may be found continues to shrink. The latest analysis of data from the CDF and DZero collider experiments at the U.S. Department of Energy’s Fermilab now excludes a significant fraction of the allowed Higgs mass range established by earlier measurements.

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.

Scientists of the CDF and DZero collaborations at the Department of Energy’s Fermi National Accelerator Laboratory have observed particle collisions that produce single top quarks.

Physicists of the DZero experiment at the U.S. Department of Energy’s Fermi National Accelerator Laboratory have discovered a new particle made of three quarks, the Omega-sub-b.

Scientists from the CDF and DZero collaborations at the U.S. Department of Energy’s Fermilab have combined Tevatron data from the two experiments to advance the quest for the long-sought Higgs boson.

Scientists of the DZero collaboration at the US Department of Energy’s Fermilab have announced the observation of pairs of Z bosons, force-carrying particles produced in proton-antiproton collisions at the Tevatron, the world’s highest-energy particle accelerator.

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.

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 processes-more than 17 trillion times per second.
