This feature is usually considered difficult to obtain based on simple group theory analyses. We reconsider a minimal toy model including the renormalisation group running at one loop.
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 A Yukawa coupling term to the Higgs field effecting spontaneous symmetry breaking in the Standard Model is responsible for fermion masses in a symmetric manner. Suppose that the potential $${\displaystyle ~V(\phi )~}$$ has its minimum, not at In the See more The Yukawa interaction is an interaction between a scalar field (or pseudoscalar field) ϕ and a Dirac field ψ of the type $${\displaystyle \quad V\approx g\,{\bar {\psi }}\,\phi \,\psi \quad }$$ (scalar) $${\displaystyle \qquad }$$ or The See more It is also possible to have a Yukawa interaction between a scalar and a Majorana field.
