The... weak force... couples to both s and s, and is very short-ranged due to the large rest mass of the messenger quanta involved. Its effective strength is usually many orders of magnitude weaker than electromagnetism, and its action can cause particles to change identity, as when a neutron decays. Unlike the electromagnetic and strong forces, the weak force violates parity conservation.
For the weak force... universality of coupling strength is not readily apparent. ic weak forces are very different in nature from ic weak processes.
How can s be produced in the center of the sun and how can they be detected in laboratories here on earth if they are subject neither to the strong force nor to the electromagnetic one? Another force, the so-called weak force, is responsible. The electron neutrino does participate in that interaction, along with the electron.
The mass of the W and Z prevents the weak force from extending beyond their Compton length (about a hundredth the size of a proton)...
