Abstract

We apply the method of QCD light-cone sum rules to calculate nonfactorizable contributions to the \stackrel\ensuremath→BJ/\ensuremathψK decay and estimate soft nonfactorizable corrections to the a₂ parameter. The corrections appear to be positive, favoring the positive sign of a₂, in agreement with recent theoretical considerations and experimental data. Our result also confirms expectations that in the color-suppressed decay nonfactorizable corrections are sizable.
