“…[7][8][9]) and with more phenomenological approaches, constraining their relative size with different experimental setups (see, e.g., refs. [10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26]). Although constructing (SU(2) L ×U(1) Y gaugeinvariant) models with large neutrino NSI and consistent with all current experimental constraints, mainly from charged-lepton flavor-violating processes, requires a certain amount of fine-tuning [9], they cannot be completely excluded.…”

Non-standard interactions in the propagation of neutrinos in matter can lead to significant deviations from expectations within the standard neutrino oscillation framework and atmospheric neutrino detectors have been considered to set constraints. However, most previous works have focused on relatively low-energy atmospheric neutrino data. Here, we consider the one-year high-energy through-going muon data in IceCube, which has been already used to search for light sterile neutrinos, to constrain new interactions in the µτ -sector. In our analysis we include several systematic uncertainties on both, the atmospheric neutrino flux and on the detector properties, which are accounted for via nuisance parameters. After considering different primary cosmic-ray spectra and hadronic interaction models, we improve over previous analysis by using the latest data and showing that systematics currently affect very little the bound on the off-diagonal ε µτ , with the 90% credible interval given by −6.0 × 10 −3 < ε µτ < 5.4 × 10 −3 , comparable to previous results. In addition, we also estimate the expected sensitivity after 10 years of collected data in IceCube and study the precision at which non-standard parameters could be determined for the case of ε µτ near its current bound.

“…The NuTeV experiment measured ν µ (ν µ ) − q scattering, where ν µ andν µ were provided by the beamline at the Fermilab [70]. Since there is relatively large systematic errors, we take a conservative limit: [55,71], which is depicted by the light yellow region.…”

Abstract:We study the right-handed neutrino (RHN) dark matter candidate in the minimal U(1) B−L gauge extension of the standard model. The U(1) B−L gauge symmetry offers three RHNs which can address the origin of the neutrino mass, the relic dark matter, and the matter-antimatter asymmetry of the universe. The lightest among the three is taken as the dark matter candidate, which is under the B − L gauge interaction. We investigate various scenarios for this dark matter candidate with the correct relic density by means of the freeze-out or freeze-in mechanism. A viable RHN dark matter mass lies in a wide range including keV to TeV scale. We emphasize the sub-electroweak scale light B − L gauge boson case, and identify the parameter region motivated from the dark matter physics, which can be tested with the planned experiments including the CERN SHiP experiment.

“…Previous studies that have constrained NSI with both oscillation and scattering experiments typically vary one or two NSI parameters when fitting to a given data set [16][17][18]. This is justifiable, considering that oscillation experiments are not able to distinguish between up/down type NSI, and specific experiments are most sensitive to only a small number of NSI parameters.…”

Accelerator and reactor complementarity in coherent neutrino-nucleus scattering

We study the complementarity between accelerator and reactor coherent elastic neutrino-nucleus elastic scattering (CEνNS) experiments for constraining new physics in the form of nonstandard neutrino interactions (NSI). First, considering just data from the recent observation by the Coherent experiment, we explore interpretive degeneracies that emerge when activating either two or four unknown NSI parameters. Next, we demonstrate that simultaneous treatment of reactor and accelerator experiments, each employing at least two distinct target materials, can break a degeneracy between up and down flavor-diagonal NSI terms that survives analysis of neutrino oscillation experiments. Considering four flavor-diagonal (ee=μμ) up-and down-type NSI parameters, we find that all terms can be measured with high local precision (to a width as small as ∼5% in Fermi units) by next-generation experiments, although discrete reflection ambiguities persist.
