A bstractWe propose a novel and simple mechanism where sizable effects of non-standard interactions (NSI) in neutrino propagation are induced from the mixing between an electrophilic second Higgs doublet and a charged singlet. The mixing arises from a dimensionful coupling of the scalar doublet and singlet to the standard model Higgs boson. In light of the small mass, the light mass eigenstate from the doublet-singlet mixing can generate much larger NSI than those induced by the heavy… 

Charged Higgs effects in IceCube: PeV events and NSIs

Abstract Extensions of the Standard Model with charged Higgs, having a non-negligible coupling with neutrinos, can have interesting implications vis-à-vis neutrino experiments. Such models can leave

Curtailing the dark side in non-standard neutrino interactions

A bstractIn presence of non-standard neutrino interactions the neutrino flavor evolution equation is affected by a degeneracy which leads to the so-called LMA-Dark solution. It requires a solar

Non-standard neutrino interactions in U(1)′ model after COHERENT data

Loop-induced neutrino non-standard interactions

A bstractNon-Standard Interactions (NSI) of neutrinos may originate from models in which new particles interact with neutrinos. In scalar extensions of the SM, the typical approach to obtain NSI

Neutrino nonstandard interactions as a portal to test flavor symmetries

Imposing non-Abelian discrete flavor symmetries on neutrino nonstandard interactions (NSIs) is discussed for the first time. For definiteness, we choose A4 as the flavor symmetry, which is

Neutrino non-standard interactions: A status report

This report summarizes the present status of neutrino non-standard interactions (NSI). After a brief overview, several aspects of NSIs are discussed, including connection to neutrino mass models,

Correlations and degeneracies among the NSI parameters with tunable beams at DUNE

The Deep Underground Neutrino Experiment (DUNE) is a leading experiment in neutrino physics which is presently under construction. DUNE aims to measure the yet unknown parameters in the three flavour
