Unexpected results from various short-baseline neutrino oscillation experiments have suggested the potential existence of a light sterile neutrino. Such a particle would affect the flux of muon neutrinos produced by accelerators in the GeV energy range; however, this attenuation has not been observed, leading to the so-called "3+1" neutrino puzzle. We have recently carried out a 3+1 sterile neutrino search using over 10 years of IceCube data of atmospheric muon neutrinos in the 0.5-100 TeV energy range. This study is unique as it explores sterile neutrinos at higher energies, testing their potential effects through both vacuum and matter-enhanced oscillations. In this seminar, I will present the latest findings from this analysis and discuss their implications within the framework of the 3+1 neutrino landscape.
