Dynamical 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...

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...

Dynamical 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...

Light 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...

Scale 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...
