Testing large non-standard neutrino interactions with arbitrary mediator mass after COHERENT data
Journal of High Energy Physics, 2018 A bstractIn the presence of neutrino Non-Standard Interactions (NSI) with matter, the derivation of neutrino parameters from oscillation data must be reconsidered.

Cosmological signatures of interacting neutrinos [PDF]
Physical Review D, 2006 We investigate signatures of neutrino scattering in the Cosmic Microwave Background (CMB) and matter power spectra, and the extent to which present cosmological data can distinguish between a free streaming or tightly coupled fluid of neutrinos. If neutrinos have strong non-standard interactions, for example, through the coupling of neutrinos to a ...

Nonstandard neutrino interactions in a modified ν2HDM [PDF]
Physical Review D, 2018 In the traditional neutrinophilic two-Higgs doublet model ($\nu$2HDM), there is no non-standard neutrino interaction (NSI) as the interactions between the Standard Model fermions with neutrinos are negligibly small due to the tiny mixing of the two ...

Theory of neutrino slow flavor evolution. Part II. Space-time evolution of linear instabilities
Journal of High Energy PhysicsSlow flavor evolution (defined as driven by neutrino masses and not necessarily “slow”) is receiving fresh attention in the context of compact astrophysical environments.

Impact of right-handed interactions on the propagation of Dirac and Majorana neutrinos in matter
, 2007 Dirac and Majorana neutrinos can be distinguished in relativistic neutrino oscillations if new right-handed interactions exist, due to their different propagation in matter. We review how these new interactions affect neutrino oscillation experiments and

Flavor changing neutrino interactions and CP violation in neutrino oscillations [PDF]
, 2002 We investigate the interference effects of non-standard neutrino-matter interactions (NSNI) with the mass-induced neutrino oscillations. The NSNI is composed of flavor-changing neutrino interactions (FCNI) and flavor-diagonal neutrino interactions (FDNI).

Non-standard neutrino interactions and low energy experiments
Journal of High Energy Physics, 2019 We formulate an Effective Field Theory (EFT) for Non Standard neutrino Interactions (NSI) in elastic scattering with light quarks, leptons, gluons and photons, including all possible operators of dimension 5, 6 and 7.

Neutrino masses in a two Higgs doublet model with a U(1) gauge symmetry
Journal of High Energy Physics, 2019 General Two Higgs Doublet Models (2HDM) are popular Standard Model extensions but feature flavor changing interactions and lack neutrino masses. We discuss a 2HDM where neutrino masses are generated via type I seesaw and propose an extension where ...

Bounds on non-standard interactions of neutrinos from IceCube DeepCore data
Journal of High Energy Physics, 2020 New physics in neutrino sector can reveal itself via non-standard neutrino in- teractions which can result in modification of the standard picture of neutrino propagation in matter.

High-energy constraints from low-energy neutrino non-standard interactions
, 2020 Many scenarios of new physics predict the existence of neutrino Non-Standard Interactions, new vector contact interactions between neutrinos and first generation fermions beyond the Standard Model.
