It seems to me that, based on the paper's abstract, the Hubble tension seems to be resolved.
In fact, the results from the Chicago Carnegie Hubble Program (CCHP) to measure the Hubble constant (Ho) using data from the James Webb Space Telescope (JWST) are statistically consistent with the Ho value derived from the Cosmic Microwave Background Radiation (CMBR).
The CCHP value of Ho ≈ 69.96 km/s/Mpc aligns with the CMBR-based estimate within the Lambda-CDM model, which is around 67.4 km/s/Mpc. This suggests no significant discrepancy between local measurements and those from the early universe, meaning no new physics is needed to explain the differences.
Indeed, I would add that if new measurements were made using the improved methods from the Chicago Carnegie Hubble Program (CCHP) and the James Webb Space Telescope (JWST) to repeat those that led to the hypothesis of the universe’s acceleration, it is highly likely that this acceleration would disappear, and there would no longer be a need to hypothesize dark energy."
