Cosmological radiation density with non-standard neutrino-electron interactions

open access: yesPhysics Letters B, 2021
Neutrino non-standard interactions (NSI) with electrons are known to alter the picture of neutrino decoupling from the cosmic plasma. NSI modify both flavour oscillations through matter effects, and the annihilation and scattering between neutrinos and ...

Measurements using the inelasticity distribution of multi-TeV neutrino interactions in IceCube [PDF]

open access: yes, 2018
Inelasticity, the fraction of a neutrino's energy transferred to hadrons, is a quantity of interest in the study of astrophysical and atmospheric neutrino interactions at multi-TeV energies with Ic ...

Constraining dark matter-neutrino interactions with IceCube-170922A [PDF]

open access: yesPhysical Review D, 2019
Astrophysical neutrinos travel long distances from their sources to the Earth traversing dark matter halos of clusters of galaxies and that of our own Milky Way. The interaction of neutrinos with dark matter may affect the flux of neutrinos.

A radiatively induced neutrino mass model with hidden local U(1) and LFV processes ℓ i → ℓ j γ, μ → eZ′ and μe → ee

open access: yesJournal of High Energy Physics, 2021
We investigate a model based on hidden U(1) X gauge symmetry in which neutrino mass is induced at one-loop level by effects of interactions among particles in hidden sector and the Standard Model leptons.

Neutrino oscillations in the interaction picture

open access: yesThe European Physical Journal C, 2023
AbstractWe study the mixing of different kind of fields (scalar in 0+1D, scalar in 3+1D, fermion in 3+1D) treating the mixing term as an interaction. To this aim, we employ the usual perturbative series in the interaction picture. We find that expression for flavor changing probability exhibits corrections with respect to the usual quantum mechanical ...

Neutrino-Nucleus Interactions [PDF]

open access: yesAnnual Review of Nuclear and Particle Science, 2011
The study of neutrino oscillations has necessitated a new generation of neutrino experiments that are exploring neutrino-nuclear scattering processes. We focus in particular on charged-current quasi-elastic scattering, a particularly important channel that has been extensively investigated both in the bubble-chamber era and by current experiments ...

Flavor-dependent long-range neutrino interactions in DUNE & T2HK: alone they constrain, together they discover

open access: yesJournal of High Energy Physics, 2023
Discovering new neutrino interactions would represent evidence of physics beyond the Standard Model. We focus on new flavor-dependent long-range neutrino interactions mediated by ultra-light mediators, with masses below 10 −10 eV, introduced by new ...

Neutrino oscillation induced by horizontal symmetry

open access: yesEurasian Journal of Physics and Functional Materials, 2021
To obtain the interactions which cause neutrino flavor conversion, we introduce a horizontal symmetry into the standard model (SM) and propose the hypothesis that new interactions generated by the horizontal symmetry lead to neutrino flavor conversion ...

Probing neutrino non-standard interactions with atmospheric neutrino data [PDF]

open access: yes, 2001
We have reconsidered the atmospheric neutrino anomaly in light of the laetst data from Super-Kamiokande contained events and from Super-Kamiokande and MACRO up-going muons.
