Weak Nuclear Force

The Weak Nuclear Force (also called the Weak Interaction) is a process that causes beta decay. This process involves a neutron turning into a proton. To do this, a neutron must not only lose in mass, but one of its quarks has to change from a down to a up quark. To do this it must eject a W boson which separates into a electron and an electron antinutrino. This decay happens in the proton-proton chain discussed here. Leptons can also emit W bosons and become corresponding nutrinos. Also, quarks can absorb or emit a Z boson. W and Z bosons are the particles that carry the Weak Nuclear force.
