Neutrinos from GRB 221009A: producing ALPs and explaining LHAASO anomalous event
Nicolás Bernal, Yasaman Farzan, Alexei Yu. Smirnov
We propose a novel explanation for the 18 TeV gamma ray from GRB 221009A observed by LHAASO. High-energy neutrinos are converted into axion-like particles (ALPs) via their interact…
Refractive neutrino masses, ultralight dark matter and cosmology
Manibrata Sen, Alexei Y. Smirnov
We consider in detail a possibility that the observed neutrino oscillations are due to refraction on ultralight scalar boson dark matter. We introduce the refractive mass squared,…
Neutrino oscillations unlocked
Alexei Y Smirnov
Space-time localization diagrams ``unlock" subtle aspects of oscillations such as coherence and entanglement. Observability of propagation decoherence in oscillating neutrino s…
GRB 221009A Gamma Rays from Radiative Decay of Heavy Neutrinos?
Alexei Y. Smirnov, Andreas Trautner
We consider a mechanism which allows to decrease attenuation of high energy gamma ray flux from gamma ray burst GRB 221009A. The mechanism is based on the existence of a heavy $m_N…
Reply to "Comment on "Damping of neutrino oscillations, decoherence and the lengths of neutrino wave packets""
Evgeny Akhmedov, Alexei Y. Smirnov
In arXiv:2209.00561 our treatment arXiv:2208.03736 of effects of particles emitted together with neutrinos on neutrino wave packets is criticized on several grounds. We show here t…
Damping of neutrino oscillations, decoherence and the lengths of neutrino wave packets
Evgeny Akhmedov, Alexei Y. Smirnov
Spatial separation of the wave packets (WPs) of neutrino mass eigenstates leads to decoherence and damping of neutrino oscillations. Damping can also be caused by finite energy res…
