Probing neutrino mass models through resonances at neutrino telescopes

We study the detection prospects of relatively light charged scalars in radiative Majorana neutrino mass models, such as Zee model and its variants using scalar leptoquarks, at current future telescopes. In particular, we show that these mediators can give rise to Glashow-like resonance features ultra-high energy (UHE) event spectrum IceCube observatory high-energy upgrade IceCube-Gen2. The same also observable non-standard interactions (NSI), UHE neutrinos provide a complementary probe NSI. discuss an interesting possibility producing resonances by incoming sterile components case where are pseudo-Dirac particles.
