Tachyonic Majorana neutrinos or neutrino spin-to-orbital angular momentum conversion in OPERA

TL;DR

This paper discusses the OPERA experiment's data supporting the existence of tachyonic Majorana neutrinos with imaginary mass and explores neutrino spin-to-orbital angular momentum conversion phenomena.

Contribution

It presents a phenomenological model of Majorana neutrinos with imaginary mass and compares simulation results with OPERA data, supporting tachyonic neutrino behavior.

Findings

Good agreement between simulations and OPERA data.

Confirmation of tachyonic behavior in neutrinos.

Discussion of spin-to-orbital angular momentum conversion.

Abstract

The new data release of OPERA - CNGS experiment, obtained with a shorter spill of protons, confirms the tachyionic behavior expected from the phenomenological model of a Majorana neutrino with a fictitious imaginary mass term acquired during the propagation in the Earth's crust, recently presented by us. We performed numerical simulations of neutrino event detections to compare the properties of these Majorana tachyons with the new OPERA results, finding a good agreement. The possibility of spin-to orbital angular momentum conversion that is expected to give a negative squared mass in a medium, is also briefly discussed.
