Apparent fake neutrino mixture due to seesaw mechanism responsible for oscillation

TL;DR

This paper proposes that neutrino flavor conversion can be explained by a seesaw mechanism involving right-handed neutrino mixtures, leading to an apparent fake neutrino mixture and a new interpretation of oscillation phenomena.

Contribution

It introduces a novel explanation for neutrino oscillations based on right-handed neutrino mixing via the seesaw mechanism, challenging traditional models.

Findings

Neutrino flavor conversion can be induced by right-handed neutrino mixture.

The transition probability is explained by boson-mediated flavor flip interactions.

Neutrino oscillation can be viewed as a macro phenomenon before flavor flip interactions reach equilibrium.

Abstract

This paper assumes that neutrino flavor conversion is induced by right-handed neutrino mixture via seesaw mechanism, which leads to apparent fake neutrino mixture with neutrino mass eigenstate consistent with flavor state of left-handed neutrino rather than mixture of flavor state. The transition probability between right-handed neutrinos due to mixture can be explained well by boson intermediating flavor flip interaction between right-handed neutrinos and neutrino oscillation can be considered macro phenomenon before all flavor flip interactions arrive at balance.
