Physical review letters 129(15), 151801 (2022). doi:10.1103/PhysRevLett.129.151801, We present a search for an unstable sterile neutrino by looking for a resonant signal in eight years of atmospheric $ν_μ$ data collected from 2011 to 2019 at the IceCube Neutrino Observatory. Both the (stable) three-neutrino and the 3+1 sterile neutrino models are disfavored relative to the unstable sterile neutrino model, though with p values of 2.8% and 0.81%, respectively, we do not observe evidence for 3+1 neutrinos with neutrino decay. The best-fit parameters for the sterile neutrino with decay model from this study are $Δm_{41}^2$ = $6.7_{-2.5}^{+3.9}$ eV$^2$, sin$^2 2θ_{24}$ = $0.33_{-0.17}^{+0.20}$, and $g^2$ = $2.5π ± 1.5π$, where $g$ is the decay-mediating coupling. The preferred regions of the 3 + 1 + decay model from short-baseline oscillation searches are excluded at 90% C.L., Published by APS, College Park, Md.
