Dalitz Plots

Great post on Dalitz plots over at Superweak, via Tommaso. Although these plots have been around since the 1950’s, they have become popular tools again to analyize the results coming out of the B factories. As described in the post it is possible to use Dalitz plots to measure the complex phases that occur in three-body decays from the interference behaviour of the plots. We use this method at Belle or BaBar to get information on the complex phase in the KM matrix.
