Weak interaction

The weak interaction is one of the four fundamental forces of nature. It is most commonly thought to be the cause of [nuclear decay]? and is carried by the W bosons (W⁺ and W^-) and [Z bosons]? (Z⁰).

The weak interaction affects:

• neutrinos
• charged leptons
• quarks

Its range is limited to within the hadron (10^-18 m). This short range is explained by the large mass of the weak exchange particles (about 90 Gev?).

The weak interaction enables all lepton? and quark particles and antiparticles interchange energy, mass and charge - effectively change in to each other.
