abstract = "Using e+e− collision data collected at the BESIII detector at center-of-mass energies between 4.128 and 4.226 GeV, corresponding to an integrated luminosity of 7.33 fb−1, we determine the absolute branching fractions of fifteen hadronic Ds+ decays with a double-tag technique. In particular, we make precise measurements of the branching fractions BDs+→K+K−π+=5.49±0.04±0.07%, BDs+→KS0K+=1.50±0.01±0.01% and BDs+→K+K−π+π0=5.50±0.05±0.11%, where the first uncertainties are statistical and the second ones are systematic. The CP asymmetries in these decays are also measured and all are found to be compatible with zero.",

N2 - Using e+e− collision data collected at the BESIII detector at center-of-mass energies between 4.128 and 4.226 GeV, corresponding to an integrated luminosity of 7.33 fb−1, we determine the absolute branching fractions of fifteen hadronic Ds+ decays with a double-tag technique. In particular, we make precise measurements of the branching fractions BDs+→K+K−π+=5.49±0.04±0.07%, BDs+→KS0K+=1.50±0.01±0.01% and BDs+→K+K−π+π0=5.50±0.05±0.11%, where the first uncertainties are statistical and the second ones are systematic. The CP asymmetries in these decays are also measured and all are found to be compatible with zero.
