A search for an eV-scale sterile neutrino using improved high-energy $ν_μ$ event reconstruction in IceCube
Published 13 May 2024 in hep-ex and hep-ph | (2405.08070v2)
Abstract: This Letter presents the result of a 3+1 sterile neutrino search using 10.7 years of IceCube data. We analyze atmospheric muon neutrinos that traverse the Earth with energies ranging from 0.5 to 100 TeV, incorporating significant improvements in modeling neutrino flux and detector response compared to earlier studies. Notably, for the first time, we categorize data into starting and through-going events, distinguishing neutrino interactions with vertices inside or outside the instrumented volume, to improve energy resolution. The best-fit point for a 3+1 model is found to be at $\sin2(2\theta_{24}) = 0.16$ and $\Delta m{2}_{41} = 3.5$ eV$2$, which agrees with previous iterations of this study. The result is consistent with the null hypothesis of no sterile neutrinos with a p-value of 3.1\%.
