In particle physics, Yukawa's interaction or Yukawa coupling, named after Hideki Yukawa, is an interaction between particles according to the Yukawa potential. Specifically, it is a scalar field (or pseudoscalar field) ϕ and a Dirac field ψ of the type $${\displaystyle ~V\approx g\,{\bar {\psi }}\,\phi \,\psi \quad }$$ See more If two fermions interact through a Yukawa interaction mediated by a Yukawa particle of mass $${\displaystyle \mu }$$, the potential between the two particles, known as the Yukawa potential, will be: See more It is also possible to have a Yukawa interaction between a scalar and a Majorana field.
