“…As we have noticed before, although one can couple the linear multiplet to gauge fields [23][24][25][26][27], one cannot write down mass terms or non-derivative interactions as in the chiral multiplet case by means of a superpotential. So, the best we can hope for is to introduce a potential indirectly by using the higher dimensional operators first discussed in [1].…”

Supersymmetry breaking by higher dimension operators

We discuss a supersymmetry breaking mechanism for N=1 theories triggered by higher dimensional operators. We consider such operators for real linear and chiral spinor superfields that break supersymmetry and reduce to the Volkov–Akulov action. We also consider supersymmetry breaking induced by a higher dimensional operator of a nonminimal scalar (complex linear) multiplet. The latter differs from the standard chiral multiplet in its auxiliary sector, which contains, in addition to the complex scalar auxiliary of a chiral superfield, a complex vector and two spinors auxiliaries. By adding an appropriate higher dimension operator, the scalar auxiliary may acquire a nonzero vev triggering spontaneous supersymmetry breaking. We find that the spectrum of the theory in the supersymmetry breaking vacuum consists of a free chiral multiplet and a constraint chiral superfield describing the goldstino. Interestingly, the latter turns out to be one of the auxiliary fermions, which becomes dynamical in the supersymmetry breaking vacuum. In all cases we are considering here, there is no sgoldstino mode and thus the goldstino does not have a superpartner. The sgoldstino is decoupled since the goldstino is one of the auxiliaries, which is propagating only in the supersymmetry breaking vacuum. We also point out how higher dimension operators introduce a potential for the propagating scalar of the theory

“…It is possible that matter fields are not accommodated into a chiral multiplet, but rather into a complex linear multiplet for example, and the same goes for the supersymmetry breaking sector. The quantum properties of complex linear supermultiplets have been studied before [24][25][26][27] and it was shown that the general quantization procedure is rather involved. If one solves the constraints by introducing prepotentials one is faced with a theory with a gauge symmetry that needs to be fixed.…”

We calculate the low energy effective action of massless and massive complex linear superfields coupled to a massive U(1) vector multiplet. Our calculations include superspace higher derivative corrections and therefore go beyond previous results. Among the superspace higher derivatives we find that terms which lead to a deformation of the auxiliary field potential and may break supersymmetry are also generated. We show that the supersymmetry breaking vacua can only be trusted if there exists a hierarchy between the higher order terms. A renormalization group analysis shows that generically a hierarchy is not generated by the quantum corrections.

We consider N = 2 supersymmetric nonlinear sigma-models in two dimensions defined in terms of the nonminimal scalar multiplet. We compute in superspace the one-loop beta function and show that the classical duality between these models and the standard ones defined in terms of chiral superfields is maintained at the quantum one-loop level. Our result provides an explicit application of the recently proposed quantization of the nonminimal scalar multiplet via the Batalin-Vilkovisky procedure. * To appear in the proceedings of Quantum aspects of gauge theories, supersymmetry and unification,
