Measurement of the $D^0\to {\pi }^{-}{e}^{+}{\nu }_e$ differential decay branching fraction as a function of $q^2$ and study of form factor parameterizations

J. P. Lees

Based on a sample of 500 million $e^{+}{e}^{-}\to c\bar{c}$ events recorded by the BaBar detector at c.m. energies of close to 10.6 GeV, we report on a study of the decay $D^0 \to π^- e^…
