Search for the radiative decay D s + → γρ 770 +
Using 7.33 fb−1 of e+e− collision data samples collected with the BESIII detector at center-of-mass energies between 4.128 and 4.226 GeV, we search for the radiative decay Ds+→γρ770+ for the first time. A hint of Ds+→γρ770+ is observed with a statistical significance of 2.5σ. The branching fraction...
