Description
We study real higher-order constraints for ${\cal N}=1$ and ${\cal N}=2$ chiral superfields, which describe spontaneously broken (to ${\cal N}=0$) and non-linearly realized supersymmetry in the presence of a light axion of a spontaneously broken global $U(1)$. For ${\cal N}=1$ the constraint is of third order, while for ${\cal N}=2$ it is of fifth order and can be imposed on abelian vector or tensor (linear) multiplet. In both cases the constraint eliminates a single real scalar (saxion) in terms of goldstino field(s).
