Abstract:
Warm inflation describes a scenario in the early universe where inflation occurs with
significant thermal interactions, leading to a sustained thermal bath that affects infla
tion dynamics and subsequent reheating processes. Although we use different models
in warm inflation, the hybrid model stands out as fascinating because it incorporates
different frameworks of high-energy physics such as SUSY, super-gravity, and GUT.
Therefore it is instructive to explore warm inflation in the hybrid model. For this,
we present a comprehensive study of warm inflation within the framework of hybrid
inflation in a non-supersymmetric model with chaotic potential λpϕp, incorporating
one-loop radiative corrections Aϕ4 ln ϕ/ϕc where A < 0. We incorporate quantum
smearing effects to investigate the consistency of resulting cosmological observables
with Planck and future experiments.
