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…
Adiabaticity and spectral splits in collective neutrino transformations
Georg G. Raffelt, Alexei Yu. Smirnov
Neutrinos streaming off a supernova core transform collectively by neutrino-neutrino interactions, leading to "spectral splits" where an energy E_split divides the transformed spec…
Unparticle constraints from SN1987A
Steen Hannestad, Georg Raffelt, Yvonne Y. Y. Wong
The existence of an unparticle sector, weakly coupled to the standard model, would have a profound impact on supernova (SN) physics. Emission of energy into the unparticle sector f…
Decoherence in supernova neutrino transformations suppressed by deleptonization
Andreu Esteban-Pretel, Sergio Pastor, Ricard Tomas +2
In the dense-neutrino region at 50-400 km above the neutrino sphere in a supernova, neutrino-neutrino interactions cause large flavor transformations. We study when the multi-angle…
Observational bounds on the cosmic radiation density
Jan Hamann, Steen Hannestad, Georg G. Raffelt +1
We consider the inference of the cosmic radiation density, traditionally parameterised as the effective number of neutrino species N_eff, from precision cosmological data. Paying p…
Exploiting the directional sensitivity of the Double Chooz near detector
Kathrin A. Hochmuth, Manfred Lindner, Georg G. Raffelt
In scintillator detectors, the forward displacement of the neutron in the reaction provides neutrino directional information as demonstrated by the CHOOZ react…
