The weak interaction participates in nuclear fission, and the theory describing it in terms of both its behavior and effects is sometimes called quantum flavourdynamics.
๐However, the term QFD is rarely usual, because the weak force is better understood in terms of electroweak theory.
๐The effective range of the weak force is limited to subatomic distances, and is less than the diameter of a proton.
๐It is one of the four familiar force-associated fundamental interactions of nature, alongside the strong interaction, electromagnetism, and gravitation.
The weak interaction affects all the fermions of the Standard Model, as well as the Higgs boson neutrinos interact only through gravity and the weak interaction.
๐At distances around 10โ18 meters, the weak interaction has a strength of a similar magnitude to the electromagnetic force, this starts to decrease exponentially with increasing distance.
๐The weak interaction has a very short effective range.
๐A particularly extreme example is the weak-force decay of a free neutron, which takes about 15 minutes.
