Inflation is a phase of accelerated expansion taking place in the early Universe. During this epoch, inhomogeneities are generated on cosmological scales from the amplification of quantum fluctuations of the gravitational and matter fields, that are stretched to distances of astrophysical interest today.
The energy scales involved in that process exceed those accessible in particle-physics experiments, hence the early Universe is a promising probe to test beyond standard-model physics. I will review the current status of constraints on high-energy models of inflation, and discuss what we may learn from future experiments.
