ACT-Planck data and phase transitions from a viable no-scale Standard Model completion
Filippo Cutrona, Francesco Rescigno, Alberto Salvio
Classically scale-invariant (and perturbative) theories provide a way to understand large hierarchies, as scales are generated through dimensional transmutation. They always lead t…
Infra-red enhanced loops in quadratic gravity
Alberto Salvio, Alessandro Strumia, Marco Vitti
It has been suggested that logarithmically enhanced infra-red loop corrections arising in theories with four derivatives correspond to a physical running of couplings, rendering qu…
Independent connection in ACTion during inflation
Alberto Salvio
The Atacama Cosmology Telescope (ACT) has recently released new measurements and constraints on inflationary observables. In this paper it is shown that a component of a dynamical…
Inflationary scenarios beyond the Standard Model
Alberto Salvio
The aim of this chapter is to explain in clear and pedagogical terms how some particle-physics models and/or mechanisms can naturally lead to inflation and how this can provide tes…
Natural Metric-Affine Inflation
Antonio Racioppi, Alberto Salvio
We consider here natural inflation in the low energy (two-derivative) metric-affine theory containing only the minimal degrees of freedom in the inflationary sector, i.e. the massl…
Inflation and Reheating through an Independent Affine Connection
Alberto Salvio
This paper is based on a talk in which I discussed how a component of the dynamical affine connection, that is independent of the metric, can drive inflation in agreement with obse…
