Abstract: (IOP)

Using events collected with the BESIII detector, we perform the first search for the weak baryonic decay . The analysis procedure is optimized using a blinded method. No significant signal is observed, and the upper limit on the branching fraction () of is set as at the 90% confidence level.

Note:
