A total neutrino conversion in the Earth without a resonance
M. V. Chizhov
TL;DR
This paper discusses the possibility of total neutrino flavor conversion in Earth's mantle-core-mantle structure, highlighting that such conversion can occur with or without resonance, and introduces a new parameterization for transition probabilities.
Contribution
It presents a novel analysis showing total neutrino conversion can happen without resonance and proposes a unified parameterization for transition probabilities.
Findings
Total neutrino conversion possible without resonance
Unified parameterization for neutrino and antineutrino transition probabilities
Analysis applicable to Earth's mantle-core-mantle structure
Abstract
The neutrino oscillation enhancement in the Earth-type medium mantle - core - mantle is discussed. It is noted that the total conversion is possible both for a resonant matter density and a nonresonant one. A useful parameterization, for the representation of the transition probability for neutrinos and antineutrinos in a single plot, is proposed.
