Axial symmetry breaking in self-induced flavor conversion of supernova neutrino fluxes
Georg Raffelt, Srdjan Sarikas, David de Sousa Seixas
Neutrino-neutrino refraction causes self-induced flavor conversion in dense neutrino fluxes. For the first time, we include the azimuth angle of neutrino propagation as an explicit…
Spurious instabilities in multiangle simulations of collective flavor conversion
Srdjan Sarikas, David de Sousa Seixas, Georg Raffelt
The dense neutrino flux streaming from a core-collapse supernova can undergo self-induced flavor conversion caused by neutrino-neutrino refraction. Numerical studies of these nonli…
Supernova neutrino halo and the suppression of self-induced flavor conversion
Srdjan Sarikas, Irene Tamborra, Georg Raffelt +2
Neutrinos streaming from a supernova (SN) core occasionally scatter in the envelope, producing a small "neutrino halo" with a much broader angle distribution than the primary flux…
Flavor stability analysis of supernova neutrino fluxes compared with simulations
Srdjan Sarikas, Georg Raffelt
We apply a linearized stability analysis to simplified models of accretion-phase neutrino fluxes streaming from a supernova. We compare the results with recent numerical studies an…
Updated BBN bounds on the cosmological lepton asymmetry for non-zero theta13
Gianpiero Mangano, Gennaro Miele, Sergio Pastor +2
We discuss the bounds on the cosmological lepton number from Big Bang Nucleosynthesis (BBN), in light of recent evidences for a large value of the neutrino mixing angle theta13. Th…
Suppression of Self-Induced Flavor Conversion in the Supernova Accretion Phase
Srdjan Sarikas, Georg G. Raffelt, Lorenz Hüdepohl +1
Self-induced flavor conversions of supernova (SN) neutrinos can strongly modify the flavor dependent fluxes. We perform a linearized flavor stability analysis with accretion-phase…
Constraining the cosmic radiation density due to lepton number with Big Bang Nucleosynthesis
G. Mangano, G. Miele, S. Pastor +2
The cosmic energy density in the form of radiation before and during Big Bang Nucleosynthesis (BBN) is typically parameterized in terms of the effective number of neutrinos N_eff.…
