Abstract
A phenomenological estimate of the branching fraction of the weak decay D{sup +} -> {theta} K{sup +} is made, which cannot be explained only through spectator processes and which is a rare process because it is a doubly Cabibbo suppressed decay. After describing the Charm Photoproduction Experiment E691, we present the results obtained in the search for this decay in the data collected by E691. These results suggest a significant contribution from W annihilation processes for the decays of the charmed meson D{sup +}. (author). 41 refs, 37 figs, 17 tabs.
