Searching for Extra Dimensions and Copies of the Standard Model with IceCube
Abstract
The hierarchy problem remains an open question in particle physics. A number of theories that address this problem lower the fundamental scale of gravity, resulting in observable consequences in the neutrino sector. In this work, we place constraints on low-scale gravity scenarios using high-energy neutrinos observed with the IceCube Neutrino Observatory. The analysis is based on 10.7 years of upward-going muon neutrino data in the energy range from 0.5 to 100 TeV. In this energy range, the theories predict characteristic spectral distortions arising from matter effects when neutrinos propagate through Earth. In the context of large extra dimension models, we constrain the compactification radius of the largest extra dimension to R ≲ 0.17 μm at 90% confidence level for both normal and inverted neutrino mass ordering. For scenarios with multiple Standard Model copies, we obtain lower limits of up to N ≳ 𝒪(400), depending on the value of the lightest neutrino mass. In parts of the parameter space, these results constitute the strongest constraints in the literature to our knowledge, while in other regions they probe previously unexplored parameter space.
