      Radiative (anti)neutrino energy spectra from muon, pion, and kaon decays

      Oleksandr Tomalak

      To describe low-energy (anti)neutrino fluxes in modern coherent elastic neutrino-nucleus scattering experiments as well as high-energy fluxes in precision-frontier projects such as the Enhanced NeUtrino BEams from kaon Tagging (ENUBET) and the Neutrinos from STORed Muons (nuSTORM), we evaluate (anti)neutrino energy spectra from radiative muon (μ−→e−ν¯eνμ(γ), μ+→e+νeν¯μ(γ)), pion πℓ2 (π−→μ−ν¯μ(γ), π+→μ+νμ(γ)), and kaon Kℓ2 (K−→μ−ν¯μ(γ), K+→μ+νμ(γ)) decays. We compare detailed O(α) distributions to the well-known tree-level results, investigate electron-mass corrections and provide energy spectra in analytical form. Radiative corrections introduce continuous and divergent spectral components near the endpoint, on top of the monochromatic tree-level meson-decay spectra, which can change the flux-averaged cross section at 6×10−5 level for the scattering on 40Ar nucleus with (anti)neutrinos from the pion decay at rest. Radiative effects modify the expected (anti)neutrino fluxes from the muon decay around the peak region by 3−4 permille, which is a precision goal for next-generation artificial neutrino sources.

      We also kindly ask you to register at your earliest convenience. The deadline for early registration is September 1, 2025.

      We encourage early-career researchers to submit a poster abstract (also by September 1). Presenters of accepted posters will be invited to give a 3-minute flash talk to advertise their work.

      Please also note that applications for financial support are part of the registration process. The registration/application should be submitted no later than August 1 to receive full consideration. Further details can be found on the conference website.

      We look forward to welcoming you to Mainz!
