Analysis of matter suppression in collective neutrino oscillations during the supernova accretion phase

Sovan Chakraborty, Tobias Fischer, Alessandro Mirizzi +2

The usual description of self-induced neutrino flavor conversions in core collapse supernovae (SNe) is based on the dominance of the neutrino density n_nu over the net electron den…

No collective neutrino flavor conversions during the supernova accretion phase

Sovan Chakraborty, Tobias Fischer, Alessandro Mirizzi +2

The large neutrino fluxes emitted with a distinct flavor hierarchy from core-collapse supernovae (SNe) during the post-bounce accretion phase, offer the best opportunity to detect…

Multi-angle effects in self-induced oscillations for different supernova neutrino fluxes

Alessandro Mirizzi, Ricard Tomàs

The non-isotropic nature of the neutrino emission from a supernova (SN) core might potentially affect the flavor evolution of the neutrino ensemble, via neutrino-neutrino interacti…

Neutrino mass hierarchy and three-flavor spectral splits of supernova neutrinos

Basudeb Dasgupta, Alessandro Mirizzi, Irene Tamborra +1

It was recently realized that three-flavor effects could peculiarly modify the development of spectral splits induced by collective oscillations, for supernova neutrinos emitted du…

Interplay between collective effects and non-standard interactions of supernova neutrinos

A. Esteban-Pretel, R. Tomas, J. W. F. Valle

We consider the effect of non-standard neutrino interactions (NSI, for short) on the propagation of neutrinos through the supernova (SN) envelope within a three-neutrino framework…

Collective flavor transitions of supernova neutrinos

Guenter Sigl, Ricard Tomas, Andreu Esteban-Pretel +4

We give a very brief overview of collective effects in neutrino oscillations in core collapse supernovae where refractive effects of neutrinos on themselves can considerably modify…

Parameter Degeneracy in Flavor-Dependent Reconstruction of Supernova Neutrino Fluxes

H. Minakata, H. Nunokawa, R. Tomas +1

We reexamine the possibility of reconstructing the initial fluxes of supernova neutrinos emitted in a future core-collapse galactic supernova explosion and detected in a Megaton-si…

Multi-angle effects in collective supernova neutrino oscillations

Andreu Esteban-Pretel, Sergio Pastor, Ricard Tomas +2

We study two-flavor collective neutrino oscillations in the dense-neutrino region above the neutrino sphere in a supernova (SN). The angular dependence of the neutrino-neutrino int…

Probing non-standard neutrino interactions with supernova neutrinos

A. Esteban-Pretel, R. Tomàs, J. W. F. Valle

We analyze the possibility of probing non-standard neutrino interactions (NSI, for short) through the detection of neutrinos produced in a future galactic supernova (SN).We conside…

Signatures of supernova neutrino oscillations in the Earth mantle and core

A. S. Dighe, M. Kachelriess, G. G. Raffelt +1

The Earth matter effects on supernova (SN) neutrinos can be identified at a single detector through peaks in the Fourier transform of their ``inverse energy'' spectrum. The positio…

Supernova pointing with low- and high-energy neutrino detectors

R. Tomas, D. Semikoz, G. G. Raffelt +2

A future galactic SN can be located several hours before the optical explosion through the MeV-neutrino burst, exploiting the directionality of --scattering in a water Cheren…

Tomography of the Earth's Core Using Supernova Neutrinos

Manfred Lindner, Tommy Ohlsson, Ricard Tomas +1

We investigate the possibility to use the neutrinos coming from a future galactic supernova explosion to perform neutrino oscillation tomography of the Earth's core. We propose to…

Probing neutrino non-standard interactions with atmospheric neutrino data

N. Fornengo, M. Maltoni, R. Tomas +1

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. We have…

Testing the principle of equivalence by supernova neutrinos

M. M. Guzzo, H. Nunokawa, R. Tomas

We study the possible impact of the neutrino oscillation which could be induced by a tiny violation of equivalence principle (VEP) for neutrinos emitted from supernova driven by gr…

Non-adiabatic level crossing in (non-) resonant neutrino oscillations

M. Kachelriess, R. Tomas

We study neutrino oscillations and the level-crossing probability $P_{LZ}=\exp(-γ_n\F_nπ/2)$ in power-law like potential profiles . After showing that the resonanc…
