68. Quasielastic interactions of monoenergetic kaon decay-at-rest neutrinos

Alexis Nikolakopoulos (UGent)

Monoenergetic muon neutrinos with an energy of 236 MeV are readily produced in intense medium-energy proton facilities at Fermilab and J-PARC when a positive kaon decays at rest ($K^+ \rightarrow \mu^+ \nu_\mu$) in the beamline absorber.
These kaon decay-at-rest (KDAR) neutrinos offer a distinctive opportunity to study neutrino-nucleus interactions without having to deal with the...

63. Assessing the accuracy of the GENIE event generator with electron-scattering data

Precision neutrino oscillation experiments of the future---of which DUNE is a prime example---require reliable event generator tools. The 1--4 GeV energy regime, in which DUNE will operate, is marked by the transition from the low-energy nuclear physics domain to that of perturbative QCD, resulting in rich and highly complex physics. Given this complexity, it is important to establish a...

60. Radiative corrections in neutrino scattering

Oleksandr Tomalak (University of Kentucky)

Neutrino physics is reaching a percent level precision and account for radiative corrections is a necessary step in modern and future accelerator-based experiments. We introduce and calculate radiative corrections in neutrino physics. Firstly, neutrino-electron scattering provides a clean tool to constrain the neutrino flux. We provide the most precise up-to-date prediction for...

19. The nucleon axial form factor in chiral perturbation theory

Fernando Alvarado (IFIC)

The nucleon axial form factor is not only a fundamental property for the understanding of hadron structure but also a key ingredient of neutrino-nucleon cross sections, whose precise knowledge is required for the analysis of neutrino oscillations. We have calculated this form factor at low momentum transfers in Baryon Chiral Effective Theory, using the extended on mass shell renormalisation...

51. Event Generators for Accelerator-Based Neutrino Experiments

William Jay

22/09/2020, 11:40

In this talk I will summarize our recent Snowmass LOI. Upcoming accelerator-based neutrino experiments present a challenging theoretical problem for the event generator community. In our letter, we highlight some of the unique challenges and suggest some possible solutions. We believe that important lessons, both technical and organizational, can be learned from the great success of the...

32. New Neutrino Interactions and Direct-Detection Experiments

Dr Yu-Dai Tsai (Fermilab)

We find that a magnetic transition dipole moment between tau and sterile neutrinos can account for the XENON1T excess events. Unlike the ordinary neutrino dipole moment, the introduction of the new sterile mass scale allows for astrophysical bounds to be suppressed. Interestingly, the best-fit regions that are compatible with the SN1987A imply either boron-8 or CNO neutrinos as the source...
