Quintessence from higher curvature supergravity

Abstract

In this contribution we revisit higher curvature N=1 supergravity and discuss the quintessence phase that can appear due to the R 4 terms. In particular we focus on the bosonic supersymmetric completion within the old-minimal and the new-minimal formulations.

On the F-term problem and quintessence supersymmetry breaking

“…The A i are the complex scalars that belong to the chiral superfields i . Models and discussions for quintessence in supergravity and in string theory can be found for example in [8,[22][23][24][25][26][27][28][29][30][31][32], a general review focused on string theory models can be found in [33] (and in [7]), and some alternative proposals in string theory can be found in [32,34,35]. Therefore we will not commit ourselves here to finding an appropriate superpotential P( i ) that gives to V SU G R A the required quintessence form.…”

“…31) which means to find the canonical χ T interactions we have to rescale (4.30) with k(τ ). Then from the consistency of the slow-roll phase one expects to have k(τ ) ∼ 10 −80 , (4.32) which means we have to redefine the fermion χ T as χ T ∼ 10 40 χ T | norm .…”
