The Higgs boson self-coupling is a phenomenon where the Higgs interacts with itself, which can manifest in particle ...

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 ...

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 ...

In the late 1960s and 1970s, researchers unified these discoveries into a single theoretical framework now known as the Standard Model of particle physics. This theory classifies all known elementary ...

Superheavy charged gravitinos may be the long-sought answer to dark matter. Dark Matter remains one of the biggest mysteries ...

Physicists are eyeing charged gravitinos—ultra-heavy, stable particles from supergravity theory—as possible Dark Matter ...

Superstring theory is not entirely beyond the reach of observation. It predicts a large negative cosmological constant and astronomers are pretty certain that the value is small positive. That's one ...

A once-promising hint of new physics from the Large Hadron Collider (LHC), the world’s largest particle accelerator, has melted away, quashing one of physicists’ best hopes for a major discovery. The ...
