Monte Carlo Simulation on Measurements of Branching Fractions for Some Exclusive Semileptonic Decays of Neutral D Mesons on BES-III

Using the Monte Carlo samples of about 800 pb^-1 and 500pb^-1 generated at and around 3.773GeV with BOSS (BESIII Offline Software System) 6.0.2 and BOSS 6.1.0, we have studied the branching fractions for D⁰ →K^-l⁺ν_l and D⁰ →πi^-l⁺ν_l (l=e, μ). According to the simulation results, the expected precision of these measurements for 20fb^-1 ψ(3770) data which will be collected on BESIII are well estimated.
