Standard and non-standard neutrino properties [PDF]

Nuclear Physics B - Proceedings Supplements, 2003
I review the interpretation of solar and atmospheric neutrino data in terms neutrino oscillations and describe some ways to account for the required neutrino masses and mixing angles from first principles, both within top-down and bottom-up approaches.

Physics implications of a combined analysis of COHERENT CsI and LAr data

Journal of High Energy Physics, 2023
The observation of coherent elastic neutrino nucleus scattering has opened the window to many physics opportunities. This process has been measured by the COHERENT Collaboration using two different targets, first CsI and then argon.

On neutrino-mediated potentials in a neutrino background

Journal of High Energy Physics, 2023
The exchange of a pair of neutrinos with Standard Model weak interactions generates a long-range force between fermions. The associated potential is extremely feeble, ∝ G F 2 / r 5 $$ {G}_F^2/{r}^5 $$ for massless neutrinos, which renders it far from ...

Investigating Lorentz Invariance Violation with the long baseline experiment P2O

Journal of High Energy Physics, 2023
One of the basic propositions of quantum field theory is Lorentz invariance. The spontaneous breaking of Lorentz symmetry at a high energy scale can be studied at low energy extensions like the Standard model in a model-independent way through effective ...

Standard and non-standard primordial neutrinos [PDF]

, 2006
The standard cosmological model predicts the existence of a cosmic neutrino background with a present density of about 110 cm^{-3} per flavour, which affects big-bang nucleosynthesis, cosmic microwave background anisotropies, and the evolution of large ...

From ray to spray: augmenting amplitudes and taming fast oscillations in fully numerical neutrino codes

Journal of High Energy Physics, 2023
In this note we describe how to complement the neutrino evolution matrix calculated at a given energy and trajectory with additional information which allows to reliably extrapolate it to nearby energies or trajectories without repeating the full ...

Effects of non-standard neutrino-electron interactions on relic neutrino decoupling [PDF]

, 2006
We consider the decoupling of neutrinos in the early Universe in presence of non-standard neutral current neutrino-electron interactions (NSI). We first discuss a semi-analytical approach to solve the relevant kinetic equations and then present the ...

Experimental tests for the Babu-Zee two-loop model of Majorana neutrino masses [PDF]

, 2006
The smallness of the observed neutrino masses might have a radiative origin. Here we revisit a specific two-loop model of neutrino mass, independently proposed by Babu and Zee.

Neutrino bound states and bound systems

Journal of High Energy Physics, 2022
Yukawa interactions of neutrinos with a new light scalar boson ϕ can lead to formation of stable bound states and bound systems of many neutrinos (ν-clusters).
