Description

With the Hubble tension recently reaching a level of around $7\sigma$ and supported from various independent directions, now it is more crucial than ever to compare the performance of different mechanisms to ease the Hubble tension. In this talk I present a fair comparison of such models dubbed the $H_0$ world cup, which serves a follow-up to the previous $H_0$ olympics. Improvements include using updated data, new models, and a more comprehensive range of Frequentist and Bayesian metrics. Beyond this baseline comparison, the $H_0$ world cup also includes curvature and CPL dark energy analyses, weighing in also on the preference for thawing dark energy with DESI BAO data in models beyond $\Lambda$CDM. In the knockout round, we investigate also if BBN or $S_8$ can impact the conclusions we draw from the comptetion.
