简介
In light of the recent muon experiment data from Fermilab, we investigate the implications of a gauged model for high energy neutrino telescopes. It has been suggested that a new gauge boson at the MeV scale can both account for the muon data and alleviate the tension in the Hubble parameter measurements. It also strikes signals at IceCube from the predicted resonance scattering between high-energy neutrinos and the cosmic neutrino background. We revisit this model based on the latest IceCube shower data, and perform a four-parameter fit to find a preferred region. We do not find evidence for secret interactions. The best-fit points of and are and , respectively, depending on assumptions regarding the absolute neutrino masses, and the secret interaction parameter space allowed by the observed IceCube data overlaps with the regions of the parameter space that can explain …
