英文摘要	We analyze the B-->KK decays with the soft-gluon corrections by using the QCD light-cone sum rules(LCSR) Although one can calculate the leading order factorization parts and the radiative corrections from hard-gluon exchanges at a. order in QCD factorization approach, it is worthwhile to estimate the nonfactorizable soft-gluon contributions from all the tree and penguin diagrams systematically. Our results show that the soft-gluon effects always decrease the branching ratios and give a few percentage corrections at most in the B-->KK decays.
