Scientists on a recent analysis looked for an unexpected number of top quark-antiquark pairs. The data (black dots) clearly favor known physics (red and green areas) and not a prediction of new physics (dashed line). In particle physics things develop pretty rapidly. The top quark was discovered in 1995 at the Fermilab Tevatron using just a few of tens of events taken over a couple of years. Nowadays, top quarks are a lot easier to come by. For instance, at…
Scientists working on the world’s leading particle collider experiments have joined forces, combined their data and produced the first joint result from Fermilab’s Tevatron and CERN’s Large Hadron Collider (LHC), past and current holders of the record for most powerful particle collider on Earth.
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 of this particle nearly 20 years in the making.
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.
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.
Batavia IL — Physicists at the Department of Energy’s Fermi National Accelerator Laboratory today (March 2) announced the discovery of the subatomic particle called the top quark, the last undiscovered quark of the six predicted by current scientific theory. Scientists worldwide had sought the top quark since the discovery of the bottom quark at Fermilab in 1977. The discovery provides strong support for the quark theory of the structure of matter. Two research papers, submitted in Friday, February 24, to…
