Neutrino Mixing and Cosmology
Nicole F. Bell
We review the consequences of neutrino mixing in the early universe. For both active-sterile mixing or mixing between three active neutrinos only, the consequences of oscillations…
Sensitivity to and in the Decaying Astrophysical Neutrino Scenario
John F. Beacom, Nicole F. Bell, Dan Hooper +2
We have previously shown that the decay of high-energy neutrinos from distant astrophysical sources would be revealed by flavor ratios that deviate strongly from the $ϕ_{ν_e}:ϕ_{ν_…
Pseudo-Dirac Neutrinos, a Challenge for Neutrino Telescopes
John F. Beacom, Nicole F. Bell, Dan Hooper +3
Neutrinos may be pseudo-Dirac states, such that each generation is actually composed of two maximally-mixed Majorana neutrinos separated by a tiny mass difference. The usual active…
Measuring Flavor Ratios of High-Energy Astrophysical Neutrinos
John F. Beacom, Nicole F. Bell, Dan Hooper +2
We discuss the prospects for next generation neutrino telescopes, such as IceCube, to measure the flavor ratios of high-energy astrophysical neutrinos. The expected flavor ratios a…
Speed-up through entanglement -- many-body effects in neutrino processes
Nicole F. Bell, Andrew A. Rawlinson, R. F. Sawyer
We study a system containing many particles of identical kinematics with a zero range interaction that scatters one from the other, and with the possible exchange of an attribute.…
