摘要We analyze the D --> pipi decay channels at the leading order, alpha(s) corrections with the QCD factorization and the soft-gluon corrections with the light cone QCD sum rule. Comparing with the experimental result, the calculations of the D-0 --> pi(+)pi(-) and D+ --> pi(+)pi(0) decay are much better under the consideration of the contributions of factorization parts, alpha(s) corrections and soft-gluon effects. However, the calculation result is one order less than the experimental result in D-0 --> pi(0)pi(0) decay. It may have large effects of final state interaction in the decay channel.
