Enhanced evidence of $X(7200)$ and improved measurements of $X(6900)$ parameters from a combined LHCb-ATLAS-CMS analysis

Bin Zhong, Ran Li, Yaqian Wang, Yuan Wang

Combining data from three LHC experiments strengthens evidence for the X(7200) and refines the X(6900) parameters in the di-J/ψ spectrum.

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 observe the X(6900) with overwhelming significance (>12σ) and ... for the X(7200), we find consistent signals across multiple interference models, with significances ranging from 3.7σ to 6.6σ; the best-fit model (adopting the CMS three-resonance scheme) yields 6.6σ significance.

C2weakest assumption

That the structures seen in the three independent experiments arise from the same physical resonances and that the chosen interference models plus background parametrizations fully capture the data without unaccounted systematic distortions or additional unknown contributions.

C3one line summary

Simultaneous fits to LHCb-ATLAS-CMS data raise X(7200) evidence to 3.7–6.6σ (best 6.6σ) while confirming X(6900) at >12σ with improved mass and width precision.
