Homework Help: Weak decay

  1. Mar 12, 2006 #1
    How do I calculate partial transition rates W if I know the Branching Ratios of the different modes? :confused:

    Remember that the branching ratio of a decay mode is just the width into that mode divided by the total width. The decay rate is just the inverse of the width. So all you need the total width, and then the branching ratios give you all the partial widths.
