A search for the rare decay of aormeson into the final stateis performed, using data collected by the LHCb experiment incollisions atand 8 TeV, corresponding to an integrated luminosity of. The observed number of signal candidates is consistent with a background-only hypothesis. Branching fraction values larger thanfor thedecay mode are excluded at 90% confidence level. For thedecay mode, branching fraction values larger thanare excluded at 90% confidence level; this is the first branching fraction limit for this decay.
