Description

Weak decay tree and annihilation-t-channel W-exchange amplitudes for the D0 → K0Sπ+π− process are calculated using quasi two-body QCD factorization approach and unitarity constraints. Final state strong Kπ and ππ interactions in S, P and D waves are described through corresponding form factors including many resonances. Preliminary results compare well with the effective mass distributions of the Belle and BABAR Collaboration analyses. (author)
