We study 
, 
, and the resonant 
, 
decays. In the final state interaction, where 
are followed by the 
to 
rescatterings, we predict 
. Due to the cancellation of the rescattering effects and the suppressed short-distance W annihilation contribution, we expect that 
. In our calculation, 
agrees with the data, whereas 
is 10 times smaller than the observation, which requires a careful examination.
