We study a variant of neutrinophilic two-Higgs doublets model to explain excess neutrino events in the 1 – 3 PeV energy bins at the IceCube. This is arranged by a charged scalar in the model, through a Glashow-like resonance. The same charged scalar can generate sizeable non standard interactions (NSIs) of the neutrinos. We perform a combined analysis of the latest IceCube observations, taking into account constraints from the neutrino and LEP experiments, to explore the parameter space leading to sizeable NSIs.
