“…Existing limits on neutrino magnetic moments are shown in blue, while the red lines indicate the future sensitivities on neutrino magnetic moments at DUNE and HK, based on our analysis, by setting magnetic field strength B 0 = 10 10 G. Note that as compared to existing limits, the sensitivity can be upgraded by two or three orders of magnitude (from O[10 −11 ] µ B JCAP09(2022)079 to O[10 −14 ] µ B ) by utilizing the neutrino spectra from the SN neutronization burst phase in forthcoming neutrino experiments like the DUNE, and HK. This is more stringent than the expected sensitivity when considering the scattering at the DUNE near detector [62]. This will have consequences for three of the most important unanswered questions in neutrino physics:…”

A core-collapse supernova (SN) offers an excellent astrophysical laboratory to test non-zero neutrino magnetic moments. In particular, the neutronization burst phase, which lasts for a few tens of milliseconds post-bounce, is dominated by electron neutrinos and can offer exceptional discovery potential for transition magnetic moments. We simulate the neutrino spectra from the burst phase in forthcoming neutrino experiments like the Deep Underground Neutrino Experiment (DUNE), and the Hyper-Kamiokande (HK), by taking into account spin-flavour conversions of supernova neutrinos caused by interactions with ambient magnetic fields. We find that the sensitivities to neutrino transition magnetic moments which can be explored by these experiments for a galactic SN are an order to several orders of magnitude better than the current terrestrial and astrophysical limits. Additionally, we also discuss how this realization might provide light on three important neutrino properties: (a) the Dirac/Majorana nature, (b) the neutrino mass ordering, and (c) the neutrino mass-generation mechanism.

“…The neutrino-electron elastic scattering cross section is calculable at the per-mille level of precision [173], and one can therefore conduct statistically-limited studies. Applications of DUNE νe scattering data include constraining the weak mixing angle [192], measuring neutrino electromagnetic properties [193], and searching for millicharged particles [178,182]. Similar strategies have been pursued using coherent elastic neutrino-nucleus scattering which also has a SM prediction at the per-mille level [194].…”

Neutrino interaction uncertainties are a limiting factor in current and next-generation experiments probing the fundamental physics of neutrinos, a unique window on physics beyond the Standard Model. Neutrino-nucleon scattering amplitudes are an important part of the neutrino interaction program. However, since all modern neutrino detectors are composed primarily of heavy nuclei, knowledge of elementary neutrino-nucleon amplitudes relies heavily on experiments performed in the 1970s and 1980s, whose statistical and systematic precision are insufficient for current needs. In this white paper, we outline the motivation for attempting measurements on hydrogen and deuterium that would improve this knowledge, and we discuss options for making these measurements either with the DUNE near detector or with a dedicated facility.
