Weak interaction theory

The weak interaction is one of the fundamental forces in nature responsible for certain types of radioactive decay and nuclear reactions. It involves subatomic particles exchanging W and Z bosons, enabling processes like the transformation of a neutron into a proton within an atom’s nucleus. Unlike gravity or electromagnetism, the weak force acts over very short distances and affects particles with certain types of properties called "weak isospin." It is essential for the universe’s evolution, including the processes that power the sun and produce elements in stars. The weak interaction is called "weak" because it is much less powerful than the strong force or electromagnetic force.
