Mind the Gap on IceCube: Cosmic neutrino spectrum and muon anomalous magnetic moment

TL;DR

This paper proposes a new leptonic U(1) gauge symmetry model to explain the IceCube cosmic neutrino spectrum gap and address the muon magnetic moment discrepancy, linking astrophysical and particle physics phenomena.

Contribution

It introduces a novel leptonic U(1) gauge symmetry that simultaneously explains the neutrino spectrum gap and the muon anomalous magnetic moment.

Findings

Reproduces the IceCube neutrino spectrum gap

Provides an additional contribution to muon g-2

Bridges astrophysical observations with particle physics anomalies

Abstract

Introducing a leptonic U(1) gauge symmetry, we try to reproduce the gap in the cosmic neutrino spectrum reported by the IceCube collaboration, and at the same time, make an additional contribution to the muon anomalous magnetic moment, which fills the gap between the standard model prediction and the experimental observation.
