dc.descriptionThe domain wall fermion formalism in lattice gauge theory is much investigated recently. This is set up by reducing 4+1 dimensional theory to low energy effective 4 dimensional one. In order to look around other possibilities of realizing chiral fermion on the lattice, we construct vortex fermion by reducing 4+2 dimensional theory to low energy effective 4 dimensional one on the lattice. In extra 2 dimensions we propose a new lattice regularization which has a discrete rotational invariance but not a translational one. In order to eliminate doubling species in the naive construction we introduce the extended Wilson term which is appropriate to our model. We propose two models for convenience and show that a normalizable zero mode solution appears at the core of the vortex.
dc.descriptionLatex 33 pages, one figure, typo corrected, references added, (v4) The errors related to $k\neq0$ zero modes, which were pointed out by Neuberger in hep-lat/0303009, are corrected. The Wilson parameter for the angular direction in extra 2 dimensions is explicitly used. The errors and typos mentioned in the erratum of NPB are corrected
