“…One simple example would be to derive constraints on active-sterile transition magnetic moments which have recently attracted significant attention (e.g. [40][41][42][43][44][45][46][47][48][49][50][51][52][53][54]). In this case the outgoing heavy sterile neutrino JHEP10(2022)041 would modify the recoil spectrum compared to the diagonal magnetic moment, requiring a detailed study.…”

We study future DUNE sensitivity to various electromagnetic couplings of neutrinos, including magnetic moments, milli-charges, and charge radii. The DUNE PRISM capabilities play a crucial role in constraining the electron flavored couplings. We find that DUNE will be able to place the strongest beam based constraint on the muon-neutrino magnetic moment by improving on LSND’s bounds by roughly a factor of two, although Borexino’s constraint from solar neutrinos will be stronger. For the muon neutrino millicharge DUNE can place the leading beam based bound, with two orders of magnitude improvement compared to the existing COHERENT constraint, suggesting that DUNE can be useful for light mediators more generally. Despite this strength, the millicharge bounds are not competitive with strong bounds from stellar cooling, beta-decay, and matter stability. Finally, DUNE may be able to test the SM prediction for the muon neutrino charge radius, by placing a constraint two times better than CHARM-II and CCFR experiments.

“…Like the light kk sterile neutrino states (light bulk neutrinos), which mix with the active neutrinos, we assume that the heavy right-handed partners (heavy bulk neutrinos) also propagate in extra dimensions. In laboratory experiments, these can be produced in the chirality flipping scattering processes through either the dipole interactions [20,[47][48][49][50][51][52][53][54][55][56][57][58][59][60] or scalar interactions [61,62], often called the up-scattering processes. The heavy bulk neutrinos produced in the final state can be related to the extra dimensions at all energy scales.…”

“…The constraints derived from the heavy right-handed neutrino masses produced through the dipole interactions in refs. [50][51][52][56][57][58] can therefore be re-evaluated for studying the sensitivity of those experiments to the extra dimensions. The relation between the weak couplings of the scalar interactions with a light mediator is also possible in models of extra dimensions [12][13][14][15].…”

We explore the possibility of relating extra dimensions with light and heavy Dirac-type neutral leptons and develop a framework for testing them in various laboratory experiments. The Kaluza-Klein modes in the large extra dimension models of the light neutral leptons could mix with the standard model neutrinos and produce observable effects in the oscillation experiments. We show that the chirality flipping up-scattering processes occurring through either neutrino magnetic dipole moment or the weakly coupled scalar interactions can also produce heavy Kaluza-Klein modes of the corresponding right-handed neutral leptons propagating in one or more extra dimensions. However, to conserve the four- dimensional energy-momentum, their masses must be below the maximum energy of the neutrinos in the initial state. The appreciable size of extra dimensions connected with these heavy neutral leptons can thus affect the cross-sections of these processes. This framework applies to any up-scattering process. Our work here focuses only on its application to the coherent elastic neutrino-nucleus scattering process. We derive constraints on the size of extra dimensions using the COHERENT data in oscillation and up-scattering processes. For model with one large extra dimension for the light neutral leptons, we obtain the limits, R ~ 3 μm (NH) and R ~ 2.5 μm (IH), on the size of extra dimension corresponding to the absolute mass limit, m0 ≤ 3 × 10−3 eV at 90% C.L. from the short-baseline oscillations. Using the up-scattering process for heavy neutral leptons, we obtain new parameter spaces between the size of extra dimensions and parameters of the dipole or scalar interactions.
