【 摘 要 】

In this talk we consider the breaking of a flavor-symmetric potential as the origin of the pseudo-Goldstone bosons responsible for inflation. The breaking of flavor symmetry generates the fermion mass hierarchy while the breaking of accidental symmetries leads to pseudo-Goldstone bosons with an axion-monodromy potential appropriate for inflation. We deal with models where the inflaton is a linear combination of two fields. We will show that the mechanism by which inflation ends depends on the choice of parameters.
