Finiteness of (4,0) supersymmetry σ models

Description

Hyper-Kahler non-linear σ models in two spacetime dimensions with (4,0) supersymmetry are ultraviolet finite due to a conspiracy of the supersymmetry and Lorentz invariances. The authors show this by performing the harmonic superspace formalism to develop (4,0) supersymmetrically covariant Feynman rules. In this framework, it is manifest that every graph is ultraviolet finite. (author)
