Abstract
Based on collision data taken at center-of-mass energy of 3.773 GeV by the BESIII detector, we report searches for the singly Cabibbo-suppressed decays and . A double tag technique is used to measure the absolute branching fractions and , with statistical significances of and , where the first and second uncertainties are statistical and systematic, respectively.
