Researchers at the Lawrence Livermore National Laboratory (LLNL) in California have made the most precise test so far of quantum electrodynamics (QED).
Since soon after its discovery by Henri Becquerel in 1896, radioactivity has been known to involve the emission of helium nuclei (alphas), electrons (betas) and photons (gammas).
Europe's premier particle-physics conference took place in 2005 on the banks of the River Tagus, near Lisbon. Per Osland and Jorma Tuominiemi report.
After six years of preparation, a 300 page article combining thousands of measurements from five different experiments presents a precision study of the properties of the Z boson.
The biennial Lepton-Photon conference was held in Uppsala on 30 June - 5 July. The talks erected the impressive edifice known as the Standard Model and showed that experimental ingenuity has not yet s...
The HCP2005 Symposium, held in the Swiss Alps, discussed the latest results from the Tevatron and the prospect that the LHC will open new scientific frontiers.
The E158 experiment at the Stanford Linear Accelerator Center has made a landmark observation: the strength of the weak force acting on two electrons lessens when the electrons are far apart.
Up to a few years ago, no significant measurement of the angle γ in the unitarity triangle of B-meson physics was expected to come out of the current B-factories.
"Table-top" experiments can still probe physics complementary to particle searches at high-energy accelerators. A beta-neutrino correlation experiment using TRIUMF's Neutral Atom Trap (TRINAT) has now...
Normal muon decay is an ideal process to investigate the electroweak interaction in the Standard Model.
