D meson decays

  1. Feb 2, 2013 #1
    Which of the following should occur at a greater rate: D0 to K(-) + (pi)(+) OR D0 to K(-) + positron + electron-flavor neutrino?
    I know that there are other decays that are Cabibbo supressed (or doubly so) but I can't see what would make one of these more likely than the other.

    I think the pdglive-tables are easier to use:

    They have a similar branching fraction, and the different phase space can lead to differences.
