Abstract
Using events collected by the Beijing Spectrum III (BESIII) detector at the Beijing Electron Positron Collider II (BEPCII) collider, we search for the hyperon semileptonic decay . No significant signal is observed and the upper limit on the branching fraction is set to be at 90% confidence level. This result is one order of magnitude more strict than the previous best limit.
