Talk title: Preheating and Particle Production in R^2-Higgs inflation

Abstract: 
In this talk, I will discuss preheating effects in $R^2$-Higgs inflation and how these effects may help connect the CMB reference scale to the inflationary energy scale. In particular, preheating driven by Goldstone bosons or, equivalently, by longitudinal gauge bosons may play a pivotal role in this connection. I will also examine how preheating dynamics may contribute to explaining the observed matter-antimatter asymmetry of the Universe.
