Non-Linear Supergravity and Inflationary Cosmology
Ignatios Antoniadis, Emilian Dudas, Fotis Farakos +1
We review a series of developments concerning non-linear realizations of supersymmetry coupled to supergravity, with emphasis on some applications to inflationary Cosmology.
On energy and particle production in cosmology: the particular case of the gravitino
Gabriele Casagrande, Emilian Dudas, Marco Peloso
It is well-known that the number of particles produced in cosmology, commonly defined in the literature from the Fock space of the instantaneous hamiltonian of the canonically norm…
A superfield constraint for N=2 --> N=0 breaking
E. Dudas, S. Ferrara, A. Sagnotti
We identify a cubic holomorphic constraint that subtends the total breaking of N=2 supersymmetry in a vector multiplet and exhibit its microscopic origin. The new constraint leaves…
Effective operators in SUSY, superfield constraints and searches for a UV completion
E. Dudas, D. M. Ghilencea
We discuss the role of a class of higher dimensional operators in 4D N=1 supersymmetric effective theories. The Lagrangian in such theories is an expansion in momenta below the sca…
Goldstino and sgoldstino in microscopic models and the constrained superfields formalism
I. Antoniadis, E. Dudas, D. M. Ghilencea
We examine the exact relation between the superconformal symmetry breaking chiral superfield (X) and the goldstino superfield in microscopic models of an arbitrary Kahler potential…
On non-universal Goldstino couplings to matter
E. Dudas, G. von Gersdorff, D. M. Ghilencea +2
Using the constrained superfields formalism to describe the interactions of a light goldstino to matter fields in supersymmetric models, we identify generalised, higher-order holom…
