We present for the first time a ghost-free higher-derivative chiral modelwith a propagating auxiliary F-term field (highest component of the chiralmultiplet). We obtain this model by removing a ghost in a higher derivativechiral model, with Higgsing it in terms of an auxiliary vector superfield.Depending on the sign of the quadratic derivative term of the chiralsuperfield, the model contains two ghost free branches of the parameterregions. We find that supersymmetry is spontaneously broken in one branch whileit is preserved in the other branch. As a consequence of dynamical F-termfield, a conserved U(1) charge corresponding to the number density of $F$appears, which can be regarded as a generalization of the R-symmetry.

Ghostbusters in higher derivative supersymmetric theories: who is afraid of propagating auxiliary fields?
