For the past half century or so, a theory known by the understated name of the Standard Model has dominated the field of particle physics. This theory provides us with a detailed description of the 17 ...

From the outside, the high-speed collisions of atomic nuclei inside particle accelerators like CERN’s Large Hadron Collider (LHC) may seem like they have very little in common with more mundane ...

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 ...

The Standard Model is our best theory for how the universe operates, but there are some missing pieces that physicists are struggling to find. When you purchase through links on our site, we may earn ...

How did the universe come into being? There are a multitude of theories on this subject. In a Physical Review Letters paper, three scientists formulate a new model: according to this, inflation, the ...

CERN’s calculation of the W boson’s mass agrees with theory, contradicting a previous anomaly that had raised the possibility of new physics. Particle’s surprise mass threatens to upend the standard ...

LOOK closely enough and almost everything we know of in the universe boils down to a handful of elementary particles. These entities constitute individual threads of the scientific masterpiece that is ...

The Standard Model is the modern physical understanding of three of the four forces of nature: electromagnetism, the strong nuclear force and the weak nuclear force. When you purchase through links on ...

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 ...

If photons possess more quantum states than expected, it would overhaul our understanding of all particle physics – and now physicists have identified a way to test this radical idea in an experiment.

Scientists have taken a major step toward solving a long-standing mystery in particle physics, by finding no sign of the ...
