Analysis of D+→K-π+e +νe and D+→K -π+μ++νμ semileptonic decays

Abstract:

Using a large sample (≈11800 events) of D+→K -π+e+νe and D+→K -π+μ+νμ decays collected by the CLEO-c detector running at the ψ(3770), we measure the helicity basis form factors free from the assumptions of spectroscopic pole dominance and provide new, accurate measurements of the absolute branching fractions for D +→K̄*0e+νe and D+→K̄*0μ+νμ decays. We find branching fractions which are consistent with previous world averages. Our measured helicity basis form factors are consistent with the sp...
