70. Present theoretical status of inflation and expected discoveries

Prof. Alexei Starobinsky

Outlined are the two simplest classes of phenomenological models of slow-roll inflation in the early Universe based either on scalar fields in General Relativity or on modified $f(R)$ gravity, their relation and basic assumptions necessary for their realization. At the present state-of-the-art, the simplest inflationary models from these classes producing the best fit to all existing...

74. Quintessential Inflation with α-attractors

Dr Konstantinos Dimopoulos (Lancaster University)

A novel approach to quintessential inflation model building is studied, within the framework of α-attractors (motivated by supergravity theories), which naturally result in a scalar potential featuring two flat regions, the inflationary plateau and the quintessential tail. The "asymptotic freedom" of α-attractors, near the kinetic poles, suppresses radiative corrections and interactions, which...
