The status of supersymmetry | symmetry magazine
The Standard Model of particle physics is both fantastically successful and glaringly incomplete. Its predictions have pieced together many of the known features of the universe and guided physicists ...

The do-it-yourself cyclotron - symmetry magazine
If the only thing amateur car builders needed was a ride to work, they wouldn’t ever build cars. While it’s certainly nice to take the finished product around the block to show the neighbors, there’s ...

The neutrino turns 60 - symmetry magazine
Solving the next neutrino mystery In the 1960s, a new mystery involving the neutrino began—this time in a gold mine in South Dakota. Ray Davis, a nuclear chemist at the DOE’s Brookhaven National ...

The Standard Model of particle physics - symmetry magazine
The Standard Model is a kind of periodic table of the elements for particle physics. But instead of listing the chemical elements, it lists the fundamental particles that make up the atoms that make ...

Nobel Prize awarded for discovery of neutrino oscillations
The 2015 Nobel Prize in Physics was awarded this morning to two physicists whose teams discovered a fundamental property of neutrinos. The work of Takaaki Kajita and Arthur B. McDonald showed that the ...

How do neutrinos get their mass? - symmetry magazine
The hidden neutrino As we experimentally observe them now, neutrinos cannot interact with the Higgs field because they’re are missing something vital: They are not right-handed. Particles can be ...

The potential of plasma wakefield acceleration - symmetry magazine
At least when it comes to particle accelerators, bigger is usually better. The bigger the particle accelerator, the more energetic its particle collisions; the more energetic the collision, the ...

What is a photon? - symmetry magazine
What physicists refer to as photons, other people might just call light. As quanta of light, photons are the smallest possible packets of electromagnetic energy. If you are reading this article on a ...

The deconstructed Standard Model equation - symmetry magazine
The Standard Model of particle physics is often visualized as a table, similar to the periodic table of elements, and used to describe particle properties, such as mass, charge and spin. The table is ...
