Weak bosons

Weak bosons are elementary particles that can be mined from weak fields. They are also known as W bosons.

With a weak boson you can convert a particle into its ‘weak partner’. This can be done on a crafting grid. For example, try the following recipe:

Downquark: 1 upquark + 1 weak boson

In this case, the upquark absorbed the weak boson and is thereby converted into a downquark. This works because the upquark and the downquark are weak partners.

Sometimes, the universe prefers one weak partner over the other. In that case the particle will convert spontaneously into its weak partner, by emitting a weak boson. For example, this happens in a neutron, which consists of two downquarks and one upquark. If you place the neutron in the world, it will convert spontaneously into a proton and a weak boson is spawned. Inside of the neutron, one of the downquarks was converted into an upquark by emitting a weak boson. Physicists call this nuclear decay.

The weak boson is not a stable particle. When you place a weak boson in the world, it will change spontaneously into an electron and an anti neutrino.

Dive deeper into the Physics: weak bosons
Weak gauge bosons are messenger particles. They transfer the weak force between particles that have a weak charge (isospin).

All matter particles have a weak charge so they can all participate in the weak nuclear force.
