abstract = "We measure the branching fractions for seven Ds+ two-body decays to pseudo-scalar mesons, by analyzing data collected at s = 4.178 ∼ 4.226 GeV with the BESIII detector at the BEPCII collider. The branching fractions are determined to beB(Ds+→K+η')=(2.68±0.17±0.17±0.08)×10−3,B(Ds+→η'π+)=(37.8±0.4±2.1±1.2)×10−3,B(Ds+→K+η)=(1.62±0.10±0.03±0.05)×10−3,B(Ds+→ηπ+)=(17.41±0.18±0.27±0.54)×10−3,B(Ds+→K+KS0)=(15.02±0.10±0.27±0.47)×10−3,B(Ds+→KS0π+)=(1.109±0.034±0.023±0.035)×10−3,B(Ds+→K+π0)=(0.748±0.049±0.018±0.035)×10−3, where the first uncertainties are statistical, the second are systematic, and the third are from external input branching fraction of the normalization mode Ds+ → K+K−π+. Precision of our measurements is significantly improved compared with that of the current world average values.",
