Naturally Light Fermions from Dimensional Reduction
We consider the 3-d Gross-Neveu model in the broken phase and construct a stable brane world by means of a domain wall and an anti-wall. Fermions of opposite chirality are localized on the walls and coupled through the 3-d bulk. At large wall separation β the 2-d correlation length diverges exponentially, hence a 2-d observer cannot distinguish this situation from a 2-d space-time. The 3-d 4-fe...
متن کاملCan fermions save large N dimensional reduction ?
This paper explores whether Eguchi-Kawai reduction for gauge theories with adjoint fermions is valid. The Eguchi-Kawai reduction relates gauge theories in different numbers of dimensions in the large N limit provided that certain conditions are met. In principle, this relation opens up the possibility of learning about the dynamics of 4D gauge theories through techniques only available in lower...
متن کاملDimensional Reduction at High Temperature for Fermions
The concept of dimensional reduction in the high temperature regime is generalized to static Green’s functions of composite operators that contain fermionic fields. The recognition of a natural kinematic region where the lowest Matsubara modes are close to their mass-shell, and the ultraviolet behavior of the running coupling constant of the original theory are crucial for providing the necessa...

متن کاملLight quark masses from Domain Wall Fermions
We present results for the renormalised light and strange quark masses calculated using Domain Wall Fermions in quenched QCD. New results using the DBW2 gauge action at a ≈ 2GeV and a ≈ 1.3GeV will be presented and compared against existing results at a ≈ 2GeV using the Wilson gauge action. This comparison allows a study of the uncertainties due to both finite lattice spacing and residual chira...
