Reheating in 3-form inflation

Understand

We consider the 3-form field, which has been considered as a candidate for realizing inflation, coupled to a scalar field which models the relativistic matter particles produced during the reheating epoch.

• We have investigated the stability conditions for this theory and found that introducing such a coupling does not lead to any ghosts or Laplacian instabilities.
• We have also investigated the reheating temperature and the production of particles due to parametric resonances.
• We have found that this process is more efficient in this theory compared to the result of the standard-scalar-field inflationary scenario.
