Description
I present a model for the color suppressed decay mode B^0 --> 2 \pi^0. The model is an extension of (heavy-light) chiral quark models.
The color suppressed (nonfactorizable) decay mode is obtained in terms of a model dependent gluon condensate. The model can account for the experimental result. Unfortunately, the theoretical result obtained within the model is very sensitive to the two model dependent parameters: The gluon condensate and the constituent light quark mass.
