SUSY breaking after inflation in supergravity with inflaton in a massive vector supermultiplet

摘要

We propose a limited class of models, describing interacting chiral multiplets with a non-minimal coupling to a vector multiplet, in curved superspace of N = 1 supergravity. Those models are suitable for the inflationary model building in supergravity with inflaton assigned to a massive vector multiplet and spontaneous SUSY breaking in Minkowski vacuum after inflation, for any values of the inflationary parameters n s and r , and any scale of SUSY breaking.
