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 ...

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 ...

An experiment deep underground hopes to explain the gallium anomaly. The gallium anomaly dates back 20 years to a confusing experimental finding. The answer could represent a fundamental shift, or it ...

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 ...

For more than half a century, particle physicists have theorized the existence of a “glueball,” a particle made entirely of gluons. While the past few decades have produced some compelling candidates, ...

Michael S Turner argues that the next breakthrough in particle physics and cosmology may be just around the corner.

It’s often said in science that extraordinary claims require extraordinary evidence. Recent measurements of the mass of the elementary particle known as the W boson provide a useful case study as to ...

THE STANDARD MODEL of particle physics—completed in 1973—is the jewel in the crown of modern physics. It predicts the properties of elementary particles and forces with mind-boggling accuracy. Take ...

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 Committee on Elementary-Particle Physics was convened by the National Research Council's Board on Physics and Astronomy to assess the field of elementary-particle physics as part of the survey ...
