A systematic search for step-like anomalies in the tritium \beta-decay spectrum in the Troitsk-\nu-mass experiment

TL;DR

This paper systematically investigates step-like anomalies in the tritium eta-decay spectrum from the Troitsk-nu-mass experiment using specialized statistical tests, concluding that the anomaly cannot be confidently confirmed.

Contribution

It introduces a systematic statistical approach to analyze step-like anomalies in eta-decay spectra, providing a more rigorous assessment of their presence.

Findings

No high-confidence evidence for the anomaly was found.

The statistical tests used are effective for anomaly detection.

The analysis refines understanding of the spectrum measurements.

Abstract

The issue of step-like anomalies in the tritium \beta-decay spectrum as measured in the Troitsk-\nu-mass experiment is addressed in the context of the new analysis in a systematic fashion using efficient statistical tests specifically derived for the purpose. It is concluded that the presence of the anomaly cannot be statistically asserted with a high confidence level.
