Cosmology Intertwined II: The Hubble Constant Tension

Cosmology and Nongalactic Astrophysics 2021-05-27 v4 High Energy Physics - Phenomenology

Abstract

The current cosmological probes have provided a fantastic confirmation of the standard Λ\Lambda Cold Dark Matter cosmological model, that has been constrained with unprecedented accuracy. However, with the increase of the experimental sensitivity a few statistically significant tensions between different independent cosmological datasets emerged. While these tensions can be in portion the result of systematic errors, the persistence after several years of accurate analysis strongly hints at cracks in the standard cosmological scenario and the need for new physics. In this Letter of Interest we will focus on the 4.4σ4.4\sigma tension between the Planck estimate of the Hubble constant H0H_0 and the SH0ES collaboration measurements. After showing the H0H_0 evaluations made from different teams using different methods and geometric calibrations, we will list a few interesting new physics models that could solve this tension and discuss how the next decade experiments will be crucial.
