Direct Proof of Reflection Positivity of Free Overlap Dirac Fermion
Yoshio Kikukawa, Kouta Usui
It is shown that free lattice Dirac fermions defined by overlap Dirac operator fulfill the Osterwalder-Schrader reflection positivity condition with respect to the link-reflection.

Reflection Positivity of N=1 Wess-Zumino model on the lattice with exact U(1)_R symmetry
Yoshio Kikukawa, Kouta Usui
By using overlap Majorana fermions, the chiral multiple can be formulated so that the supersymmetry is manifest and the vacuum energy is cancelled in the free limit, t…
