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

Collins asymmetries in lepton-proton processes allow for a much clearer access to the transversity distribution, including its sea-quark component.

C2weakest assumption

That the transversity and Collins fragmentation functions extracted from SIDIS and e+e- annihilation can be directly applied here under the assumption of TMD factorization and Collins universality, which the paper aims to test but does not independently verify.

C3one line summary

Collins asymmetries for pion-in-jet production in polarized lepton-proton collisions provide clearer access to transversity distributions at the EIC and test the universality of the Collins function.
