Width effects in resonant three-body decays: B decay as an example

For three-body hadron decays mediated by intermediate resonances with large widths, we show how to properly extract the quasi-two-body decay rates for a meaningful comparison with the corresponding theoretical estimates, using several B decays as explicit examples. We compute the correction factor f...
