Energy-dependent slow collective flavor conversion of supernova neutrinos
Heng-Hao Chen, Ian Padilla-Gay, Meng-Ru Wu +2
We study collective slow flavor conversion (SFC) of supernova neutrinos with multi-energy, multi-angle simulations for three representative neutrino spectra in the early accretion,…
Solar-System Abundances of -Nuclides Probe Collective Neutrino Oscillations in Supernovae
Alexander Friedland, Derek J. Li, Giuseppe Lucente +3
Direct evidence for collective neutrino oscillations in core-collapse supernovae remains elusive. We show that this quantum phenomenon leaves a footprint on the abundance pattern o…
Neutrino Flavor Transformation in Collapsing Supermassive Objects
Kyle S. Kehrer, George M. Fuller, Ian Padilla-Gay +1
The collapse of supermassive stars (SMSs, ) to black holes is accompanied by a prodigious flux of neutrinos of all flavors. These are produced thermally via…
-process in Core-Collapse Supernovae: Imprints of General Relativistic Effects
Alexander Friedland, Derek J. Li, Giuseppe Lucente +2
The origin of a number of proton-rich isotopes in the solar system has been a long-standing puzzle. A promising explanation is the -process, which is posited to operate in the…
Flavor Equilibration of Supernova Neutrinos: Exploring the Dynamics of Slow Modes
Ian Padilla-Gay, Heng-Hao Chen, Sajad Abbar +2
Neutrinos experience collective flavor conversion in extreme astrophysical environments such as core-collapse supernovae (CCSNe). One manifestation of collective conversion is slow…
Symmetry breaking due to multi-angle matter-neutrino resonance in neutron star merger remnants
Ian Padilla-Gay, Shashank Shalgar, Irene Tamborra
Neutron star merger remnants are unique sites for exploring neutrino flavor conversion in dense media. Because of the natural excess of over , the neutrino-neutrino…
Collisions and collective flavor conversion: Integrating out the fast dynamics
Damiano F. G. Fiorillo, Ian Padilla-Gay, Georg G. Raffelt
In dense astrophysical environments, notably core-collapse supernovae and neutron star mergers, neutrino-neutrino forward scattering can spawn flavor conversion on very short scale…
Neutrino Fast Flavor Pendulum. Part 2: Collisional Damping
Ian Padilla-Gay, Irene Tamborra, Georg G. Raffelt
In compact astrophysical objects, the neutrino density can be so high that neutrino-neutrino refraction can lead to fast flavor conversion of the kind $ν_e \barν_e \leftrightarrow…
Neutrino Flavor Pendulum Reloaded: The Case of Fast Pairwise Conversion
Ian Padilla-Gay, Irene Tamborra, Georg G. Raffelt
In core-collapse supernovae or compact binary merger remnants, neutrino-neutrino refraction can spawn fast pair conversion of the type (wi…
Fast flavor conversion of neutrinos in presence of matter bulk velocity
Ian Padilla-Gay, Shashank Shalgar
A dense gas of neutrinos and antineutrinos can undergo fast pairwise conversions near the decoupling regions of core-collapse supernovae and in compact binary neutron star mergers.…
A three Higgs doublet model with symmetry-suppressed flavour changing neutral currents
Dipankar Das, P. M. Ferreira, António P. Morais +3
We construct a three-Higgs doublet model with a flavour non-universal symmetry. That symmetry induces suppressed flavour-changing interactions media…
Multi-Dimensional Solution of Fast Neutrino Conversions in Binary Neutron Star Merger Remnants
Ian Padilla-Gay, Shashank Shalgar, Irene Tamborra
Fast pairwise conversions of neutrinos are predicted to be ubiquitous in neutron star merger remnants with potentially major implications on the nucleosynthesis of the elements hea…
Neutrino propagation hinders fast pairwise flavor conversions
Shashank Shalgar, Ian Padilla-Gay, Irene Tamborra
Neutrino flavor conversions may dramatically affect the inner working of compact astrophysical objects as well as the synthesis of the heavier elements. We present the first sophis…
