In particle physics, a Yukawa potential (also called a screened Coulomb potential) is a potential of the form
where g is a magnitude scaling constant, m is the mass of the affected particle, r is the radial distance to the particle, and k is another scaling constant. The potential is monotone increasing, implying that the force is always attractive.
In interactions between a meson field and a fermion field, the constant g is equal to the coupling constant between those fields. In the case of the nuclear force, the fermions would be a proton and another proton or a neutron.

Famous quotes containing the word potential:
“Silence is as full of potential wisdom and wit as the unhewn marble of great sculpture. The silent bear no witness against themselves.”
—Aldous Huxley (1894–1963)
