Description
We present the first-ever search for Long-Lived Particles (LLPs) produced by atmospheric muons with the IceCube neutrino telescope.
Atmospheric muons, disregarded as background in most IceCube analyses, could produce LLPs in the detector volume via an exotic muon–nucleus bremsstrahlung-like scattering, which would travel undetected for some distance before decaying back into Standard Model particles, creating a distinct “dark gap" segment in the otherwise bright muon track. Identifying these rare signatures within the sparse detector geometry is a significant challenge, but provides a probe into new physics scenarios involving feebly interacting particles with long lifetimes.
