When a $\\tau$ neutrino ($\\nu_\\tau$) enters the Earth it produces $\\tau$ leptons as a result of nuclear charged current interactions. In some cases, this process results in a $\\tau$ lepton exiting the surface of the Earth, which can subsequently decay in the atmosphere and produce an extensive air shower. These upward-going air showers can be detected via fluorescence, optical Cherenkov, or geomagnetic radio emission. Several experiments have been proposed to detect these signals. We present a comprehensive simulation of the production of $\\tau$ leptons by $\\nu_\\tau$'s propagating through Earth to aid the design of future experiments. These simulations for $\\nu_\\tau$'s and leptons in the energy range from $10^{15}$ eV to $10^{21}$ eV treat the full range of incidence angles from Earth-skimming to diametrically-traversing. Propagation of $\\nu_\\tau$'s and leptons include the effects of rock and an ocean or ice layer of various thicknesses. The interaction models include $\\nu_\\tau$ regeneration and account for uncertainties in the Standard Model neutrino cross-section and in the photo-nuclear contribution to the $\\tau$ energy loss rate.","url_abs":"http://arxiv.org/abs/1707.00334v4","url_pdf":"http://arxiv.org/pdf/1707.00334v4.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":"a-comprehensive-approach-to-tau-lepton","repo_url":"https://github.com/harmscho/NuTauSim","is_official":1,"mentioned_in_paper":1,"mentioned_in_github":1,"framework":"none","reach":null},{"paper_slug":"a-comprehensive-approach-to-tau-lepton","repo_url":"https://github.com/aucummin/NuMuSim","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null},{"paper_slug":"a-comprehensive-approach-to-tau-lepton","repo_url":"https://github.com/ryankrebs016/NuLeptonSim","is_official":0,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":null}],"tasks":[],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[],"syntology":{"syntology_url":null,"atlas_url":null,"mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
