Looking for antineutrino flux from $^{40}$K with large liquid scintillator detector

TL;DR

This paper explores the potential to detect antineutrinos from potassium-40 within the Earth using large liquid scintillator detectors, aiming to improve understanding of Earth's thermal flux.

Contribution

It introduces the concept of detecting Earth's $^{40}$K antineutrino flux and provides bounds on its possible magnitude.

Findings

Lower and upper limits on $^{40}$K antineutrino flux are established.

Detection of this flux could enhance understanding of Earth's thermal processes.

Abstract

We regard the possibility of detecting the antineutrino flux producing by the $^{40}$K placing inside the Earth. Thermal flux of the Earth could be better understood with observing such a flux. Lower and upper limitations on the $^{40}$K antineutrino flux are presented.
