How to build supersymmetry lagrangians

[Neitrino]

Hi,

In SUSY we introduce chiral superfield, vector superfield, then build some invariants and get the SUSY lagrangians which after decomposition into normal fields (F and D terms) gives us for example ordinary QED plus some other terms. And we call this SUSY-QED.

I have following question suppose i have some toy lagrangian of ordinary fields and I want to have its SUSY extension (when I "decompose" SUSY lagrangian I want to get my toy lagrangian) could you pls advise on this issue how should this procedure run ? or any references ?

Thank you very much

How about trying to promote your non-SUSY independent variables to be functions on superspace, and then try to construct your SUSY action using that formalism?
