# Highlights from the 7 year High Energy Starting Event sample in Icecube

## TL;DR

This paper summarizes seven years of IceCube's High Energy Starting Events, emphasizing new physics searches with astrophysical neutrino flavor data that probe energy scales up to the Planck level.

## Contribution

It presents the longest IceCube HESE dataset and introduces a novel physics search reaching the Planck scale using neutrino flavor data.

## Key findings

- Seven years of HESE data collected
- First physics search reaching the Planck scale
- Insights into astrophysical neutrino flavor composition

## Abstract

Here we outline the main highlights from the 7 year High Energy Starting Events (HESE) event sample. The next new physics search using astrophysical neutrino flavor data is described, where we reach the Planck scale for the first time.
