Goldstino couplings to matter.
A nonlinearly realized supersymmetric action describing the invariant couplings of the Goldstino to matter is constructed. Using the Akulov-Volkov Lagrangian, any operator can be made part of a supersymmetric invariant action. Of particular interest are interaction terms which include the product of the Akulov-Volkov Lagrangian with the ordinary matter Lagrangian as well as the coupling of the ...

متن کاملMatter couplings in partially broken extended supersymmetry
We use nonlinear realizations to describe the spontaneous breaking of N = 2 su-persymmetry to N = 1 in four dimensions. We identify the Goldstone multiplet with an N = 1 chiral superfield, and show that chiral N = 1 matter is consistent with the partially broken N = 2 supersymmetry. We find that the chiral matter can be in any representation of the gauge group; no mirror particles are required....
متن کاملBelinfante Tensors Induced by Matter-gravity Couplings
We show that any generally covariant coupling of matter fields to gravity gives rise to a conserved, on-shell symmetric energy-momentum tensor equivalent to the canonical energy-momentum tensor of the flat-space theory. For matter fields minimally coupled to gravity our algorithm gives the conventional Belinfante tensor. We establish that different matter-gravity couplings give metric energy-mo...
متن کاملGeneralized Curvature-Matter Couplings in Modified Gravity
In this work, we review a plethora of modified theories of gravity with generalized curvature-matter couplings. The explicit nonminimal couplings, for instance, between an arbitrary function of the scalar curvature R and the Lagrangian density of matter, induces a non-vanishing covariant derivative of the energy-momentum tensor, implying non-geodesic motion and, consequently, leads to the appea...
