Abstract

Using dispersion theoretic techniques, we consider coherent long range forces arising from double pseudoscalar exchange among fermions. We find that Yukawa type coupling leads to 1/r³ spin-independent attractive potentials whereas derivative coupling renders 1/r⁵ spin-independent repulsive potentials.
