Strong constraints on neutrino nonstandard interactions from TeV-scale $ν_μ$ disappearance at IceCube

R. Abbasi,
M. Ackermann,
J. Adams
et al.

Abstract: We report a search for nonstandard neutrino interactions (NSI) using eight years of TeV-scale atmospheric muon neutrino data from the IceCube Neutrino Observatory. By reconstructing incident energies and zenith angles for atmospheric neutrino events, this analysis presents unified confidence intervals for the NSI parameter µτ . The best-fit value is consistent with no NSI at a p-value of 25.2%. With a 90% confidence interval of −0.0041 ≤ µτ ≤ 0.0031 along the real axis and similar strength in the complex plane… Show more

“…High-energy neutrino telescopes are suitable detectors to search for NSI-induced deviations since they are expected to increase with the distance travelled through matter and with energy. Limits on NSIs from atmospheric neutrinos have already been reported by the Super-Kamiokande Collaboration [17] or using Super-Kamiokande data [18], and by the IceCube Collaboration [19][20][21] or using IceCube data [22][23][24].…”

“…ple, DeepCore has an effective 10 Mton volume recorded over 300, 000 neutrino events in the eight years run. Neutrino telescopes can use large sample sizes to study the ν μ disappearance and ν τ appearance channels to look for new physics through neutrino oscillations [410,[778][779][780][781], and tank detectors use all channels however much smaller sample sizes. Thus, detector tanks designed for accelerator-based neutrino experiments and neutrino telescopes designed for extraterrestrial neutrino detection overlap in this energy region but differences in technologies make them complimentary.…”

“…In an experimental first, a 3-year DeepCore O(GeV) all-flavour analysis provided sensitivity to all NSI matrix elements simultaneously, lepton flavour universality violating and flavour changing alike, with competitive or leading limits upon each [15]. These efforts are complementary to O(TeV) track analyses from IceCube which have a strong sensitivity to flavourchanging NSI element, 𝜖 𝜇 𝜏 [16]. An 8-year analysis is underway for DeepCore's all-flavour NSI.…”
