In the 1990s, the Liquid Scintillator Neutrino Detector (LSND) in Los Alamos, New Mexico, found a weird anomaly during its experiments on tiny elementary particles called neutrinos. It found far more ...

Weak bosons are elementary particles that mediate weak interactions in particle physics. Weak bosons were predicted to exist theoretically in 1968, and their existence was confirmed in 1983 by the ...

There’s something amiss with a mass. A new measurement of the mass of an elementary particle, the W boson, has defied expectations. The result hints at a possible flaw in physicists’ otherwise ...

The results of a high-profile Fermilab physics experiment appear to confirm strange 20-year-old findings that poke holes in the standard model, suggesting the existence of a new elementary particle: a ...

In a weak moment, researchers have found an unexpected asymmetry in particle production that could hint at exotic physics. The tentative evidence, announced August 21, could be the fingerprint of a ...

A collaboration of hundreds of scientists have precisely measured the mass of the W boson, an elementary particle responsible for the weak nuclear force. The researchers found, to their surprise, that ...

Ten years ago, scientists announced the discovery of the Higgs boson, which helps explain why elementary particles (the smallest building blocks of nature) have mass. When you purchase through links ...

Physicists have found that an elementary particle called the W boson appears to be 0.1% too heavy — a tiny discrepancy that could foreshadow a huge shift in fundamental physics. The measurement, ...

The first big physics story of the year is not hard to understand if its two sides are appreciated. There is a particle called a muon, which is related to the electron but is much bigger and is highly ...

Scientists reviewed three experiments that hint at a phenomenon beyond the Standard Model of particle physics, outlines a new report. To anyone but a physicist, it sounds like something out of "Star ...
