Nonfactorization and Color-Suppressed B→ψ(ψ(2S))+K( K ∗ ) Decays
Abstract
Using
N
c
=3
value of the parameter
a
2
=0.09
but including a modest nonfactorized amplitude, we show that it is possible to understand all data, including polarization, for color-suppressed
B→ψ(ψ(2S))+K(
K
∗
)
decays in all commonly used models of form factors. We show that for
B→ψ+K
decay one can define an effective
a
2
, which is process-dependent and, in general, complex; but it is not possible to define an effective
a
2
for
B→ψ+
K
∗
decay. We also explain why nonfactorized amplitudes do not play a significant role in color-favored B decays.
