Dynamical generation of fermion mass in a scalar-fermion theory with λϕ4 interaction

A bstract The effective potential for a scalar theory with λϕ 4 interaction, coupled to a massless fermion through Yukawa interaction is calculated by summing over infinite number of two particle irreducible (2PI) diagrams of two different types and a 2PI diagram of a third type...
