Claims

C1strongest claim

The Reactor Antineutrino Anomaly is revived at the level of 2.2 sigma with the 2023 French summation model flux calculation, and a global fit including gallium data yields 3.8 sigma tension that reduces to 1.3 sigma with enlarged gallium uncertainties.

C2weakest assumption

That the 2023 summation model provides a more accurate central value and uncertainty budget than the 2021 models, and that the observed rate deficit is not dominated by unaccounted experimental systematics in the reactor measurements themselves.

C3one line summary

A 2023 reactor antineutrino flux calculation revives the Reactor Antineutrino Anomaly to 2.2 sigma and produces 3.8 sigma tension with gallium data that drops to 1.3 sigma when gallium uncertainties are enlarged.
