Analytic treatment of 3-flavor neutrino oscillation and decay in matter
Journal of High Energy Physics, 2023 We present compact analytic expressions for 3-flavor neutrino oscillation probabilities with invisible neutrino decay, where matter effects have been explicitly included.

Journal of High Energy Physics, 2022 Non-standard neutrino interactions with a massive boson can produce the bosons in the core of core-collapse supernovae (SNe). After the emission of the bosons from the SN core, their subsequent decays into neutrinos can modify the SN neutrino flux.

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).

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 ...

Quantum decoherence and relaxation in long-baseline neutrino data
Journal of High Energy Physics, 2023 We investigate the effect of quantum decoherence and relaxation in neutrino oscillations using MINOS and T2K data. The formalism of open quantum systems is used to describe the interaction of a neutrino system with the environment, where the strength of ...

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 ...

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 ...

Microscopic and macroscopic effects in the decoherence of neutrino oscillations
Journal of High Energy Physics, 2022 We present a generic structure (the layer structure) for decoherence effects in neutrino oscillations, which includes decoherence from quantum mechanical and classical uncertainties. The calculation is done by combining the concept of open quantum system

Testing non-standard neutrino interactions in (anti)-electron neutrino disappearance experiments
Journal of High Energy Physics, 2023 We search for scalar and tensor non-standard interactions using (anti)-electron neutrino disappearance in oscillation data. We found a slight preference for non-zero CP violation, coming from both tensor and scalar interactions.
