Neutrino decoupling including flavour oscillations and primordial nucleosynthesis [PDF]
Journal of Cosmology and Astroparticle Physics, 2020 We revisit the decoupling of neutrinos in the early universe with flavour oscillations. We rederive the quantum kinetic equations which determine the neutrino evolution based on a BBGKY-like hierarchy, and include for the first time the full collision ...

Neutrino velocity and neutrino oscillations [PDF]
Physical Review D, 2012 We study distances of propagation and the group velocities of the muon neutrinos in the presence of mixing and oscillations assuming that Lorentz invariance holds. Oscillations lead to distortion of the $ _ $ wave packet which, in turn, changes the group velocity and the distance $ _ $ travels. We find that the change of the distance, $d_{osc}$, is

Testing moduli and flavon dynamics with neutrino oscillations [PDF]
Journal of High Energy Physics, 2020 We study scalar Non-Standard Neutrino Interactions (NSI) induced by moduli or flavon exchange between electrons and neutrinos. In a region with non-vanishing electron number density, they are known to determine a shift of the neutrino mass matrix.

Neutrino Masses and Oscillations [PDF]
Advances in High Energy Physics, 2014 The year 2013 marks the 100th anniversary of the birth of Bruno Pontecorvo, who first suggested the possibility that neutrinos might have a nonzero mass such that oscillations among different neutrino states might occur. Pontecorvo constantly pursued this idea, after the discovery of other neutrino flavours, until his death. This issue is intended as a

Potential Impact of Fast Flavor Oscillations on Neutrino-driven Winds and Their Nucleosynthesis [PDF]
Astrophysical Journal, 2020 The wind driven by the intense neutrino emission from a protoneutron star (PNS) is an important site for producing nuclei heavier than the Fe group. Because of certain features in the neutrino angular distributions, the so-called fast flavor oscillations

ATMOSPHERIC NEUTRINO OSCILLATIONS [PDF]
Non-Accelerator Astroparticle Physics, 2002 The recent results from the Soudan 2, MACRO and SuperKamiokande experiments on atmospheric neutrino oscillations are summarized and discussed. Some features of possible future atmospheric neutrino experiments are presented.

Massless neutrino oscillations [PDF]
Physical Review D, 2001 Quantum dynamical semigroups provide a general framework for studying the evolution of open systems. Neutrino propagation both in vacuum and in matter can be analyzed using these techniques: they allow a consistent treatment of non-standard, dissipative effects that can alter the pattern of neutrino oscillations.

Updated global analysis of neutrino oscillations in the presence of eV-scale sterile neutrinos [PDF]
Journal of High Energy Physics, 2018 We discuss the possibility to explain the anomalies in short-baseline neutrino oscillation experiments in terms of sterile neutrinos. We work in a 3 + 1 framework and pay special attention to recent new data from reactor experiments, IceCube and MINOS ...
