Dubbed SMASH, the model is based on the standard model of particle physics, but has a few bits tacked on. The standard model is a collection of particles and forces that describes the building blocks ...

It is a branch of physics concerned with how baryons were originally formed. Baryons are a family of subatomic particles and, like other subatomic particles, have their opposite category called ...

Each charged elementary particle has a counterpart with the opposite charge, which is known as an antiparticle. The antiparticle partner of the negative electron, for example, is the positive positron ...

Where were we? Ah yes, spontaneous symmetry breaking. When some field takes on a nonzero value even in empty space, and that field is affected by some symmetry transformation, the resulting symmetry ...
