Lattice chiral symmetry, CP-violation and Majorana fermions
نویسنده
چکیده
A brief summary of lattice fermions defined by the general Ginsparg-Wilson algebra is first given. It is then shown that those general class of fermion operators have a conflict with CP invariance in chiral gauge theory and with the definition of Majorana fermions in the presence of chiral-symmetric Yukawa couplings. The same conclusion holds for the domain-wall fermion also.

Domain wall fermion and CP symmetry breaking
We examine the CP properties of chiral gauge theory defined by a formulation of the domain wall fermion, where the light field variables q and q̄ together with Pauli-Villars fields Q and Q̄ are utilized. It is shown that this domain wall representation in the infinite flavor limit N = ∞ is valid only in the topologically trivial sector, and that the conflict among lattice chiral symmetry, strict ...
متن کاملOverlap Formulation of Majorana–weyl Fermions
An overlap method for regularizing Majorana–Weyl fermions interacting with gauge fields is presented. A mod(2) index is introduced in relation to the anomalous violation of a discrete global chiral symmetry. Most of the paper is restricted to 2 dimensions but generalizations to 2+8k dimensions should be straightforward.
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 کاملBK from quenched QCD with exact chiral symmetry.
We present a calculation of the standard model DeltaS=2 matrix element relevant to indirect CP violation in K-->pipi decays which uses Neuberger's chiral formulation of lattice fermions. The computation is performed in the quenched approximation on a 16(3) x 32 lattice that has a lattice spacing a approximately 0.1 fm. The resulting bare matrix element is renormalized nonperturbatively. Our mai...
