Exact lattice supersymmetry in a non-commutative framework

Presenter: Alessandro D'Adda — INFN - Sezione di Torino

Following the formalism developed in recent papers a one dimensional model with two supercharges is formulated on the lattice keeping all supersymmetries exact. The role of non-commutative geometry is emphasized, and the modified Leibnitz rule on the lattice is interpreted as the result of a Moyal product. Recent claims of inconsistency of the formalism are discussed and shown not to be relevant.
