About 80% of the universe's mass is thought to consist of dark matter. Yet, little is known about the composition and ...

Quick facts about particle physics Number of known elementary particles: 61 The particles that are in an atom: protons, neutrons and electrons The particles that are in protons and neutrons ...

The CMS collaboration analysed Higgs-boson decays to two photons, setting limits on anomalous couplings that would violate CP ...

Superconducting sensors can detect single low-energy photons. UZH researchers have now used this capability to search for ...

What do quarks, electrons, and photons have in common? They’re all part of the Standard Model - the theory that helped ...

Rubidium atoms that are chilled to extremely low temperatures could emit bursts of particles called neutrinos.

A relatively small detector caught neutrinos from a nuclear reactor using a technique known as coherent scattering ...

Particle physicists also use results from ground- and space-based telescopes to study the elementary particles and the forces that govern their interactions. This latter category of experiments ...

Majorana particles offer a promising solution for stable quantum computing, utilizing nonlocal encoding and topological ...

Why so many “elementary” particles? Why four forces? How do dark matter, dark energy, gravity and space-time fit in? Answering these questions is the work of elementary particle physics.

Although the LHC has ruled out many permutations of supersymmetry (SUSY)—a set of theories positing that elementary particles have “superparticle” partners—one culprit that could be ...

Using machine learning, string theorists are finally showing how microscopic configurations of extra dimensions translate into sets of elementary particles—though not yet those of our universe.
