“…4, agree with experimental data from the BaBar [23] and CLEO [33] Collaborations. The calculated total branching fractions are also in good agreement with averaged experimental values from PDG [1] and recent data from the BES III Collaboration [2][3][4][5][6][7][8][9][10]. To test lepton universality in the semileptonic D (s) meson decays we calculated the ratios of the branching fractions of decays involving muons to the ones involving positrons.…”

“…Good agreement in the whole accessible kinematical range is observed. In Tables V-VII we compare our and previous theoretical predictions [26,27,30] with experimental data from PDG [1] and recent data from BES III [2][3][4][5][6][7][8][9][10] Collaboration. We roughly estimate the uncertainties of our calculations to be within 10%.…”

“…with the decay constants f q ¼ ð1.07 AE 0.02Þf π and f s ¼ ð1.34 AE 0.06Þf π for η q and η s , respectively, and the mixing angle ϕ ¼ 39.3°AE 1.0°, which is close to the recent measurement ϕ ¼ ð40.1 AE 1.4 stat AE 0.5 syst Þ°by the BESIII Collaboration [58]. The wave functions for the states π; K; η q , and η s in this work are written as…”
