Classical Potential
If two fermions interact through a Yukawa interaction with Yukawa particle mass, the potential between the two particles, known as the Yukawa potential, will be:
which is the same as a Coulomb potential except for the sign and the exponential factor. The sign will make the interaction attractive between all particles (the electromagnetic interaction is repulsive for identical particles). This is explained by the fact that the Yukawa particle has spin zero and even spin always results in an attractive potential. The exponential will give the interaction a finite range, so that particles at great distances will hardly interact any longer.

Famous quotes containing the words classical and/or potential:
“Against classical philosophy: thinking about eternity or the immensity of the universe does not lessen my unhappiness.”
—Mason Cooley (b. 1927)
“It can be fairly argued that the highest priority for mankind is to save itself from extinction. However, it can also be argued that a society that neglects its children and robs them of their human potential can extinguish itself without an external enemy.”
—Selma Fraiberg (20th century)
