Hi,

I'm reading Seiberg-Witten's "Monopole condensation and

confinement..."-paper and I have a basic question.

When you write down the N=2 SUSY Lagrangian in terms of N=1

superfields, there is a requisite N=1 superpotential term of the form

\sqrt{2} \tilde{Q} \Phi Q ,

which is required for N=2 SUSY.

I understand this fact and I can explicitly verify that it's true. But

suppose we didn't know it, how can we derive it? Do we have to guess

the presence of such a term and find its prefactor by explicit

computation? I hope there is a simpler and more straightforward way...
