There are many theoretical proposals to remove the tension, with work still needed on that front. However, by looking at new probes of the $H_0$ parameter one can get new insights that might ease the tension. Here, we argue that neutrino oscillations could be such a probe. We expand on previous work and study the full three-flavor neutrino oscillations within the $\\Lambda$CDM paradigm. We show how the oscillation probabilities evolve differently with redshift for different values of $H_0$ and neutrino mass hierarchies. We also point out how this affects neutrino fluxes which, from their measurements at neutrino telescopes, would determine which value of $H_0$ is probed by this technique, thus establishing the aforementioned aim.","url_abs":"https://arxiv.org/abs/2111.15249v2","url_pdf":"https://arxiv.org/pdf/2111.15249v2.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"links_only","authors_date_abstract":"arXiv metadata, CC0 1.0 (https://info.arxiv.org/help/license), from the Kaggle arXiv metadata snapshot of 2026-09-12"},"code_links":[{"paper_slug":"using-neutrino-oscillations-to-measure-h-0","repo_url":"https://github.com/ark93-cosmo/neutrinooscillation-h0tension","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":0,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
