Decay of High-Energy Astrophysical Neutrinos
John F. Beacom, Nicole F. Bell, Dan Hooper +2
Existing limits on the non-radiative decay of one neutrino to another plus a massless particle (e.g., a singlet Majoron) are very weak. The best limits on the lifetime to mass rati…
State permutations from manipulation of near level-crossings
Nicole F. Bell, R. F. Sawyer, Raymond R. Volkas +1
We discuss some systematic methods for implementing state manipulations in systems formally similar to chains of a few spins with nearest-neighbor interactions, arranged such that…
Do solar neutrinos decay?
John F. Beacom, Nicole F. Bell
Despite the fact that the solar neutrino flux is now well-understood in the context of matter-affected neutrino mixing, we find that it is not yet possible to set a strong and mode…
Stringent Constraints on Cosmological Neutrino-Antineutrino Asymmetries from Synchronized Flavor Transformation
Kevork N. Abazajian, John F. Beacom, Nicole F. Bell
We assess a mechanism which can transform neutrino-antineutrino asymmetries between flavors in the early universe, and confirm that such transformation is unavoidable in the near b…
