Abstract
We apply the method of QCD light-cone sum rules to calculate nonfactorizable contributions to the B -> J/psi K decay and estimate soft nonfactorizable corrections to the a_2 parameter. The corrections appear to be positive, favoring the positive sign of a_2, in agreement with recent theoretical considerations and experimental data. Our result also confirms expectations that in the color-suppressed decay nonfactorizable corrections are sizable.
