Usingof electron-positron collision data recorded by the BESIII detector at center-of-mass energies between 4.178 and 4.226 GeV, we present the first search for the decay,, which could proceed viamixing. No significant signal is observed. An upper limit ofat the 90% confidence level is set on the product of the branching fractions ofanddecays.
