# Zee-Burst: A New Probe of Neutrino Non-Standard Interactions at IceCube

## TL;DR

This paper introduces a novel method to detect neutrino non-standard interactions using ultra-high energy neutrino data at IceCube, focusing on the Zee model which predicts observable resonance features from light charged scalars.

## Contribution

It proposes using the Zee model's charged scalars to identify NSI effects in UHE neutrino spectra at IceCube and IceCube-Gen2, a new approach in neutrino physics.

## Key findings

- Potential to observe Glashow-like resonance features in UHE neutrino spectrum.
- Probing a significant portion of NSI parameter space with current and future detectors.
- Light charged scalars in the Zee model can induce detectable NSI effects.

## Abstract

We propose a new way to probe non-standard interactions (NSI) of neutrinos with matter using the ultra-high energy (UHE) neutrino data at current and future neutrino telescopes. We consider the Zee model of radiative neutrino mass generation as a prototype, which allows two charged scalars -- one $SU(2)_L$-doublet and one singlet, both being leptophilic, to be as light as 100 GeV, thereby inducing potentially observable NSI with electrons. We show that these light charged Zee-scalars could give rise to a Glashow-like resonance feature in the UHE neutrino event spectrum at the IceCube neutrino observatory and its high-energy upgrade IceCube-Gen2, which can probe a sizable fraction of the allowed NSI parameter space.
