Combined, these results are important steps towards solving the 35-year-old puzzle of how νSI impact supernovaeģ. For the wind-outflow case, we outline several promising ideas that may lead to new observables. In the burst-outflow case, νSI increase the duration of the neutrino signal, and even a simple analysis of SN 1987A data has powerful sensitivity. Though the diffusive environment where neutrinos are produced may make a wind more likely, further work is needed to determine when each case is realized. The outflow becomes either a burst or a steady-state wind which occurs here is uncertain. We show that νSI make neutrinos form a tightly coupled fluid that expands under relativistic hydrodynamics. For the high neutrino densities within core-collapse supernovae, νSI could be important, but robust observables have been lacking. As an example, enhanced self-interactions (νSI), which would have broad implications, are allowed. HirataĪbstract : Neutrinos remain mysterious. Towards Powerful Probes of Neutrino Self-Interactions in Supernovae( arXiv )Īuthor : Po-Wen Chang, Ivan Esteban, John F. We have emphasized the need of better theoretical models for some of these processes for studying the nuclear medium effects in nucleiĢ. This study would be helpful in understanding the (anti)neutrino interaction cross section with matter in the few GeV energy region relevant to the next generation experiments like DUNE, Hyper-Kamiokande, and other experiments with accelerator and atmospheric neutrinos. In some cases the results of the cross sections are also given and compared with the available experimental data as well as with the predictions in the different theoretical models. The importance of nuclear medium effects in the low, intermediate and high energy regions, in the above processes along with the processes of the coherent neutrino-nucleus scattering, coherent meson production, and trident production, have been highlighted. The polarization observables for the leptons and hadrons produced in the final state, in the case of quasielastic scattering, are also studied. The different (anti)neutrino processes like the quasielastic scattering, inelastic production of mesons and hyperons, and the deep inelastic scattering from the free nucleons are discussed and the results for the scattering cross sections are presented.
