Speaker
Description
The topic of this talk will be a new inflationary model called ‘Loop Blow-Up Inflation’, first presented in 2403.04831. This model originates from string theory, by including string loop corrections in the potential of a blow-up Kähler modulus, a scalar field playing the role of the inflaton. The loop effects become dominant as soon as the inflaton is displaced from its post-inflationary minimum, giving rise to an inflationary potential with an inverse-power law behaviour. This talk will focus mostly on the post-inflationary history and reheating mechanisms predicted for different brane set-ups that realize the Standard Model. The predictions for the spectral index, the tensor-to-scalar ratio, and dark radiation are in good agreement with CMB data.
