Perturbative Ultraviolet Calculations in Supergravity,n side, the duality between color and kinematics proposed in [.] has opened new avenues for constructing supergravity amplitude integrands at relatively high loop order. In this talk, I explain how the color-kinematics duality is used to construct gravity integrands, and I detail how to extract ultr

Our formalism allows one to write a supergravity extension of any higher-derivative scalar field theory and therefore has applications to both particle physics and co

Expanded around this vacuum, the scalar sector is shown to be ghost-free with no spatial gradient instabilities. The fermion sector is found to consist of a massless chiral fermion an

In contrast with the standard superfield approach in which unbroken supersymmetry plays the leading role, we have shifted the attention to the spontaneously broken supersymmetry. It turns out that in the theories in which one half of supersymmetries is spontaneously b

Supersymmetric cubic Galileons are shown to imply equations of motion of higher than second order, thus leading to the appearance of ghosts.
