Search for the baryonic decay $ D_{s}^{*+} \to \ p \bar{n} $
Abstract
The first search for the baryonic decay $ D_{s}^{*+} \to \ p \bar{n} $ is performed using e+e- collision data taken at center-of-mass energies between 4.128 and 4.226 GeV, collected by the BESIII experiment and corresponding to an integrated luminosity of 7.33 fb−1. No significant signal is observed, and an upper limit on the branching fraction is set to be 1.3× 10−4 at the 90% confidence level.
