The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We find that the W²-based estimator shows the smallest bias as a function of true neutrino energy and it is particularly stable against the mismodelling of lepton scattering angle and momentum, missing energy, hadronic invariant mass and final state interactions.

C2weakest assumption

That the toy long-baseline oscillation analysis and the assumed mismodelling scenarios sufficiently capture the dominant uncertainties present in real LArTPC data taking and reconstruction.

C3one line summary

The W²-based estimator shows the smallest bias versus true neutrino energy and greater stability to mismodelling of scattering and interactions than four common alternatives in LArTPC experiments.
