Reflection Positivity of Free Overlap Fermions
arXiv:1005.3751 · doi:10.1103/PhysRevD.82.114503
Abstract
It is shown that free lattice fermions defined by overlap Dirac operator fulfill the Osterwalder-Schrader reflection positivity condition with respect to the link-reflection. The proof holds true in non-gauge models with interactions such as chiral Yukawa models.
arXiv comment16pages, the proof for Weyl fermions and chiral Yukawa model are explained in some detail, references added. This version will appear in Physical Review D
