Résumé fourni par la source

We search, for the first time, for an exotic molecular state with quantum numbers J P C = 1 − + , called X , via the process e + e − → γ D s + D s 1 − ( 2536 ) + c . c . using data samples corresponding to a luminosity of 5.8 fb − 1 across center-of-mass energies from 4.612 to 4.951 GeV , collected with the BESIII detector operating at the BEPCII Collider. No statistically significant signal is observed. The upper limits on the product of cross section and branching fraction σ ( e + e − → γ X ) · B ( X → D s + D s 1 − ( 2536 ) + c . c . ) at 90% confidence level are reported for each energy point, assuming the X mass to be 4.503 GeV / c 2 and the width 25, 50, 75, and 100 MeV , respectively.

Ce résumé expose les affirmations des auteurs. BNTIC ne l’interprète pas comme une validation indépendante des résultats.
