Fermion mass without symmetry breaking
نویسنده
چکیده
We examine a model of reduced staggered fermions in three dimensions interacting through an SO(4) invariant four fermion interaction. The model is similar to that considered in a recent paper by Ayyer and Chandrasekharan [1]. We present theoretical arguments and numerical evidence which support the idea that the system develops a mass gap for sufficiently strong four fermi coupling.without producing a symmetry breaking fermion bilinear condensate. Massless and massive phases appear to be separated by a continuous phase transition. ar X iv :1 51 0. 04 15 3v 3 [ he pla t] 7 J an 2 01 6

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...

A electroweak theory without spontaneous symmetry breaking is studied in this paper. A new symmetry breaking of SU(2)L × U(1), axial-vector symmetry breaking, caused by the combination of the axial-vector component of the intermediate boson and the fermion mass is found in electroweak theory. The mass of the W boson is resulted in the combination of the axial-vector symmetry breaking and the ex...

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 کاملGauge independence and chiral symmetry breaking in a strong magnetic field
The gauge independence of the dynamical fermion mass generated through chiral symmetry breaking in QED in a strong, constant external magnetic field is critically examined. We present a (first, to the best of our knowledge) consistent truncation of the Schwinger-Dyson equations in the lowest Landau level approximation. We demonstrate that the dynamical fermion mass, obtained as the solution of ...
