The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons: quarks The four fundamental forces: gravity, electromagnetism, the strong force and ...

In particle physics, data long outlives the detectors that generate it. A decade ago the 4,100-metric-ton Collider Detector at Fermilab (CDF) reached the end of its life and was shut down, stripped of ...

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...

Javier Duarte kicked off his scientific career by witnessing the biggest particle physics event in decades. On July 4, 2012, scientists at the laboratory CERN near Geneva announced the discovery of ...

A model for the structure of the electron is proposed, in which the electron is composed of electric tripole, i.e., a +1 ...

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 ...

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 ...

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, ...

Physicists are spelunking the complex findings from an experimental particle reactor found a mile below the surface in the mountains of Russia. What they found has the potential to send an earthquake ...

Add Yahoo as a preferred source to see more of our stories on Google. For more than half a century, particle physicists have theorized the existence of a “glueball,” a particle made entirely of gluons ...

Previous chapters have shown that the great successes of the past quarter of a century in elementary-particle physics are embodied in the Standard Model, which contains both the electroweak ...
