Systematic search for step-like anomalies in the tritium β-decay spectrum in the Troitsk-ν-mass experiment

The issue of step-like anomalies in the tritium β-decay spectrum as measured in the Troitsk-ν-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.
