# Particle Physics Models of Inflation

@inproceedings{Lyth2007ParticlePM, title={Particle Physics Models of Inflation}, author={David H. Lyth}, year={2007} }

Inflation models are compared with observation on the assumption that the curvature perturbation is generated from the vacuum fluctuation of the inflaton field. The focus is on single-field models with canonical kinetic terms, classified as small- medium- and large-field according to the variation of the inflaton field while cosmological scales leave the horizon. Small-field models are constructed according to the usual paradigm for beyond Standard Model physics
