Dynamical fermion mass generation by a strong Yukawa interaction
We consider a model with global Abelian chiral symmetry of two massless fermion fields interacting with a complex massive scalar field. We argue that the Schwinger–Dyson equations for the fermion and boson propagators admit ultraviolet-finite chiral-symmetry-breaking solutions provided the Yukawa couplings are large enough. The fermions acquire masses and the elementary excitations of the compl...
متن کاملDynamical Low-mass Fermion Generation in Randall-sundrum Background *
It is investigated that a dynamical mechanism to generate a low mass fermion in Randall-Sundrum (RS) background. We consider a five-dimensional four-fermion interaction model with two kinds of bulk fermion fields and take all the mass scale in the five-dimensional spacetime at the Planck scale. Evaluating the effective potential of the induced four-dimensional model, I calculate the dynamically...
متن کاملLight fermion mass generation in dynamical symmetry breaking
We reconsider the question of mass generation for fermions coupled to a set of gauge bosons (in particular, the electroweak gauge bosons) when the latter get their masses through the Goldstone bosons originating in a simple (i.e. not extended) technicolor sector. The fermion global chiral symmetries are broken by including four-fermion interactions. We find that the system can be nonperturbativ...
متن کاملDynamical Generation of Fermion Mass and Magnetic Field inThree -
We study dynamical symmetry breaking in three-dimensional QED with Chern-Simons term, considering the screening eeect of N avor fermions. We nd a new phase of vacuum, on which both fermion mass and magnetic eld are dynamically generated, when the coeecient of Chern-Simons term equals N e 2 =4. The resultant vacuum becomes the nite density state half lled by fermions. For = Ne 2 =2, we nd the fe...
متن کاملScale of fermion mass generation
Unitarity of longitudinal weak vector boson scattering implies an upper bound on the scale of electroweak symmetry breaking, Λ EW SB ≡ √ 8πv ≈ 1 TeV. Appelquist and Chanowitz have derived an analogous upper bound on the scale of fermion mass generation , proportional to v 2 /m f , by considering the scattering of same-helicity fermions into pairs of longitudinal weak vector bosons in a theory w...
