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 introduce a novel Statistical Reconstruction method that allows extracting information of target single-particle sources relative to a data-constrained reference source instead of the Gaussian assumption... enabling a direct statistical reconstruction of the single-particle emission source, instead of inferring a pair source. The reconstructed source reproduces the key characteristics and this new approche achieves a systematic uncertainty of approximately 13% based on EPOS4 simulation.

C2weakest assumption

The assumption that the single-particle-conditioned correlation kernel distribution is experimentally accessible and can be transformed to event-by-event extraction without significant bias from the choice of reference source or the accuracy of external HAL QCD potentials; also that the EPOS4HQ simulation faithfully represents real collision dynamics for validation.

C3one line summary

A statistical method reconstructs single-particle emission sources for rare particles directly from conditioned correlation kernels in femtoscopy, demonstrated on simulated J/ψ sources in pp collisions with 13% systematic uncertainty.
