Charged Higgs effects in IceCube: PeV events and NSIs

A bstract Extensions of the Standard Model with charged Higgs, having a non-negligible coupling neutrinos, can have interesting implications vis-à-vis neutrino experiments. Such models leave their footprints not only in ultra-high energy detectors like IceCube but also give rise to non-standard interactions (NSIs). We consider model based on neutrinophilic two-Higgs doublets and study its imprints excess events 1–3 PeV bins at IceCube. This is facilitated by existence scalar which result Glashow-like resonance. The same be responsible for sizeable NSIs. perform combined latest data along various other constraints arising from different experiments together limits set LEP experiment, explore parameter space lead NSI.
