Sažetak
We apply the method of QCD light-cone sum rules to calculate nonfactorizable contributions to the B-->J/psiK 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.
