Abstract

We calculate the process- and polarization-dependent nonfactorizable terms +AFw-widetildea_+AFw-lambda of the B+AFw-to J/+AFw-Psi +AFw-rm K^* decay within the QCD-improved factorization approach. The longitudinal part +AFw-widetildea₀ is infrared convergent and large enough to agree with recent experimental data, provided that the B-K^* form factors A₁(m²_+AFw-Psi) and A₂(m²_+AFw-Psi) satisfy some constraints met by many (but not all) models. The transverse parts +AFw-widetildea_+AFw-pm on the other hand are infrared divergent, the procedure used to handle such divergence is discussed in relation with the B+AFw-to J/+AFw-Psi +AFw-rm K case in which the same problem arises. Our nonzero phases of the helicity amplitudes are consistent with experimental data recently measured for the first time by the BaBar collaboration.
