The X17 Existence Hinted at by Nuclear Reactor Neutrinos

TL;DR

This paper suggests that neutrino data from nuclear reactors and other experiments support the existence of the X17 particle, potentially explaining anomalies observed in nuclear physics.

Contribution

It demonstrates how CEvNS data combined with neutrino experiments can indicate the presence of the X17 particle, a novel approach in particle physics research.

Findings

Reactor neutrino experiments support the X17 particle hypothesis.

Combined data from multiple sources narrows down X17 coupling parameters.

Analysis corroborates previous hints of X17 from nuclear anomaly experiments.

Abstract

We show how, by exploiting the process of Coherent Elastic neutrino (v) Nucleus Scattering (CEvNS), neutrinos produced by nuclear reactor experiments appear to corroborate the evidence of the so-called X17 particle, which has been invoked to explain the ATOMKI anomaly. We base our analysis primarily on CONUS+ and Dresden-II data, which, when combined with CEvNS data from COHERENT and neutrino oscillation data from IceCube, single out a unique region of couplings to neutrinos and nuclei.
