Brownian motion of neutrinos in the Sun [On the distribution of collisions of a neutrino with nucleons of the Sun]

TL;DR

This paper investigates the impact of neutrino Brownian motion in the Sun, considering a new neutrino-nucleon interaction, and models collision distributions to match observed solar neutrino data.

Contribution

It introduces a geometric distribution model for neutrino collisions, improving agreement with experimental data and confirming the effective collision method under a new interaction hypothesis.

Findings

Good agreement with observed solar neutrino processes

Flux ratio of left- and right-handed neutrinos near 0.516:0.484

Validation of the effective collision number method

Abstract

When solving the solar neutrino problem on the basis of the hypothesis of the existence of a new interaction between electron neutrinos and nucleons, carried by a massless pseudoscalar boson, it becomes necessary to find the consequences of the short-term Brownian motion of neutrinos in the Sun. Earlier, we transmitted these consequences by the effective number of collisions of a neutrino with nucleons of the Sun, assuming the equality of fluxes near the Earth of left- and right-handed solar neutrinos. In this paper, we analyze the transfer of the mentioned consequences by a test geometric distribution of collisions with one free parameter. This distribution provides good agreement between theoretical and experimental results for all five observed processes with solar neutrinos, while it gives the ratio of fluxes near the Earth of left- and right-handed neutrinos equal to 0.516:0.484. With such a ratio, the acceptability of the method of the effective number of collisions of a neutrino with nucleons is again confirmed.
