Abstract: Using e+e annihilation data corresponding to an integrated luminosity of 3.19 fb1 collected at a center-of-mass energy of 4.178 GeV with the BESIII detector, we measure the absolute branching fractions BDs+ηe+νe=(2.323±0.063stat±0.063syst)% and BDs+ηe+νe=(0.824±0.073stat±0.027syst)% via a tagged analysis technique, where one Ds is fully reconstructed in a hadronic mode. Combining these measurements with previous BESIII measurements of BD+η()e+νe, the ηη mixing angle in the quark flavor basis is determined to be ϕP=(40.1±2.1stat±0.7syst)°. From the first measurements of the dynamics of Ds+η()e+νe decays, the products of the hadronic form factors f+η()(0) and the Cabibbo-Kobayashi-Maskawa matrix element |Vcs| are determined with different form factor parametrizations. For the two-parameter series expansion, the results are f+η(0)|Vcs|=0.4455±0.0053stat±0.0044syst and f+η(0)|Vcs|=0.477±0.049stat±0.011syst.
