A New Solution to Ginsparg-Wilson Relation from Generalized Staggered Fermion
نویسندگان
چکیده
A generalized anti-hermitian staggered Dirac operator is formulated. Its relation with noncommutative geometry is briefly reviewed. Once this antihermitian operator is modified to be “γ5-hermitian”, it will provide a new solution to Ginsparg-Wilson relation, basing on an abstract algebraic analysis of Neuberger’s overlap construction and a redefinition of chirality.

A Lattice Fermion Doublet With A Generalization Of The Ginsparg-Wilson Relation
We present a new staggered discretization of the Dirac operator. In comparison with standard staggered fermions, real and imaginary parts are located in different nodes. Doubling gives only a doublet of Dirac fermions which we propose to interpret as a physical (lepton or quark) doublet. Contrary to usual staggered fermions, we have no exact chiral symmetry but obtain a generalization of the Gi...
متن کاملExactly massless fermions on the Lattice
My talk at Lattice 98 essentially consisted of two parts : (1) The general solution of the Ginsparg-Wilson (GW) relation; (2) Some numerical results for the ( generalized ) NeubergerDirac fermion operator. In this writeup, due to the page limit, I confine my discussions to the second part of which I did not have enough time to cover in my talk. For the first part, I refer to ref. [5] and ref. [...
متن کاملGinsparg-Wilson operators and a no-go theorem
If one uses a general class of Ginsparg-Wilson operators, it is known that CP symmetry is spoiled in chiral gauge theory for a finite lattice spacing and the Majorana fermion is not defined in the presence of chiral symmetric Yukawa couplings. We summarize these properties in the form of a theorem for the general GinspargWilson relation. The Ginsparg-Wilson relation[1] provides a convenient fra...
متن کاملA Criterium for the Index Theorem on the Lattice with the Ginsparg Wilson Relation
The Ginsparg Wilson Relation and the Neuberger action recently improved the understanding of the Index Theorem on the lattice, however this problem has not been solved yet. With the presently available criteria, we develop a technique based on the position of roots and poles to build a new simple solution of the Ginsparg Wilson Relation. In the free fermion case, we study the roots, the poles, ...
متن کاملLow energy effective action of domain-wall fermion and the Ginsparg-Wilson relation
We derive the effective action of the light fermion field of the domain-wall fermion, which is referred as q(x) by Furman and Shamir. The inverse of the effective Dirac operator turns out to be identical to the inverse of the truncated overlap Dirac operator, except a local contact term which would give the chiral symmetry breaking in the Ginsparg-Wilson relation. This result allows us to relat...
