N2 - The singly Cabibbo suppressed decay Λc+→pη′ is measured using 4.5 fb-1 of e+e-collision data collected at center-of-mass energies between 4.600 and 4.699 GeV with the BESIII detector at BEPCII. Evidence for Λc+→pη′ with a statistical significance of 3.6σ is reported with a double-Tag approach. The Λc+→pη′ absolute branching fraction is determined to be (5.62-2.04+2.46±0.26)×10-4, where the first and second uncertainties are statistical and systematic, respectively. Our result is consistent with the branching fraction obtained by the Belle collaboration within the uncertainty of 1σ.
