The Language of <strong>SUSY</strong>LagrangiansKinetic terms <strong>for</strong> Chiral superfields, and derivative interactions followfrom a real-valued function – the Kähler potential, K (·, ·):∫ () ∫L ⊃ d 2 θd 2 θ K Φ † , e gT a V a Φ = d 2 θd 2 θ Φ † e gV ΦTo restrict attention to renormalizable interactions, it <strong>is</strong> sufficient toconsider the canonical Kähler potential.Non-derivative interactions follow from a holomorphic function calledthe Superpotential, W (·).
