Search for the radiative transition χ_ (c1)(3872)→ γψ₂ (3823). arXiv, (2405.07741 v1).24700010http://dx.doi.org/10.1103/PhysRevD.110.012012https://hdl.handle.net/20.500.12713/6880Using Formula Presented of Formula Presented collision data collected at center-of-mass energies from 4.178 to 4.278 GeV with the BESIII detector at the BEPCII collider, we perform the first search for the radiative transition Formula Presented. No signal is observed and the upper limit on the ratio of branching fractions Formula Presented is set at 0.075 at the 90% confidence level. Our result contradicts theoretical predictions under the assumption that the Formula Presented is the pure charmonium state Formula Presented.
