That's a gauge symmetry: when a symmetry transformation can be separately carried out at different points in space. Gauge symmetries are sometimes called local symmetries since we can do them ...

Quantum gravity requires that any internal gauge symmetry (which implies conservation laws like electric charge, color charge, or weak isospin) is mathematically compact.

Without this critical gauge symmetry associated with electroweak symmetry breaking, existence wouldn't be possible, as we do not have stable, bound states made purely of massless particles.

Gauge symmetry is familiar in classical electromagnetism and in general relativity, and it is central in the standard model.

Learn about the standard model of particle physics, the most accurate physical theory yet.

Even though gauge symmetry is something that most people find obscure, it’s the most visible thing in the world—and if you don’t have it, things fall apart in surprising ways.

Symmetry is everywhere in our natural world. Just take a look at your hands, a butterfly, or a sunflower. It’s easy to pass off the idea of symmetry and symmetric structures as a simple quir… ...

Gauge symmetry “dictates what other ingredients you have to introduce.” It’s roughly the same kind of symmetry as the one that tells us that a triangle that’s invariant under 120-degree rotations must ...

Cosmic weather gauges Particle physics joins forces with other fields to look at two important factors shaping weather: temperatures high in the atmosphere and the dampness of the dirt beneath our ...
