The weak force acts on particle that have weak hypercharge, just as electromagnetism acts on objects with electrical charge and gravity acts on objects with mass. All the quarks and leptons have weak hypercharge, so the weak force act on them. The description you have been given of beta decay is incomplete because it does not conserve the overall lepton ...


The "forces" used in current Standard Model of physics (the quotes are on purpose since there are other forces as well, in different context), are: "Strong Nuclear Force", in essence keeps the nuclei together, nuclear fission is based on this "Weak Nuclear force", in essence is a type of nuclear force (associated with nuclei) but has a smaller coupling ...


Gluons are the bosons associated with the strong nuclear force. The particles W and Z are the bosons associated with weak nuclear force. The strong nuclear force holds quarks together to make nucleons.
