Search for the radiative transition χ_{c1}(3872)\toγ ψ_2(3823)

Using 9.0 \rm fb^{-1} of e^+e^- 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 \chi_{c1}(3872)\to\gamma \psi_2(3823). No \chi_{c1}(3872)\to\gamma \psi_2(3823) signal is observed. The upper limit on the ratio of branching... Show more
