Studies of the Cabibbo-suppressed decays D+ → π0ℓ+v and D+ → ηe+ve
Using 4.8 fb-1 of data taken with the CLEO II detector, the branching fraction for the Cabibbo suppressed decay D+ → π0ℓ+v measured relative to the Cabibbo favored decay D+ → K0̄ℓ+v is found to be 0.046 ± 0.014 ± 0.017. Using Vcs and Vcd from unitarity constraints, we determine |fπ+(0) / fK+(0)|2 =...
