Note on arXiv:2005.05301, 'Preparation of the Neutrino-4 experiment on search for sterile neutrino and the obtained results of measurements'

Understand

We comment on the claimed observation [arXiv:arXiv:2005.05301] of sterile neutrino oscillations by the Neutrino-4 collaboration.

• Such a claim, which requires the existence of a new fundamental particle, demands a level of rigor commensurate with its impact.
• The burden lies with the Neutrino-4 collaboration to provide the information necessary to prove the validity of their claim to the community.
• In this note, we describe aspects of both the data and analysis method that might lead to an oscillation signature arising from a null experiment and describe additional information needed from the Neutrino-4 collaboration to support the oscillation claim.
