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:
“And what is the potential man, after all? Is he not the sum of all that is human? Divine, in other words?”
—Henry Miller (1891–1980)
