摘要：

We report a study of the decay D-0 -> (K) over bar (0)pi(-)e(+)nu(e) based on a sample of 2.93 fb(-1) e(+)e(-) annihilation data collected at the center-of-mass energy of 3.773 GeV with the BESIII detector at the BEPCII collider. The total branching fraction is determined to be B(D-0 -> (K) over bar (0)pi(-)e(+)nu(e)) = (1.434 +/- 0.029(stat.) +/- 0.032(syst.))%, which is the most precise to date. According to a detailed analysis of the involved dynamics, we find this decay is dominated with the K*(892)(-) contribution and present an improved measurement of its branching fraction to be B(D-0 -> K*(892)(-)e(+)nu(e) = (2.033 +/- 0.046(stat.) +/- 0.047(syst.))%. We further access their hadronic form-factor ratios for the first time as r(V) = V(0)/A(1)(0) = 1.46 +/- 0.07(stat.) +/- 0.02(syst.) and r(2) = A(2)(0)/A(1)(0) = 0.67 +/- 0.06(stat.) +/- 0.01(syst.). In addition, we observe a significant (K) over bar (0)pi(-) S-wave component accounting for (5.51 +/- 0.97(stat.) +/- 0.62(syst.))% of the total decay rate.
