CP violation in multibody B decays from QCD factorization
Journal of High Energy Physics
We test a data-driven approach based on QCD factorization for charmless three-body B-decays by confronting it to measurements of CP violation in B^- →π^- π^+ π^-. While some of the needed non-perturbative objects can be directly extracted from data, some others can, so far, only be modelled. Although this approach is currently model dependent, we comment on the perspectives to reduce this model dependence. While our model naturally accommodates the gross features of the Dalitz distribution, itdoi:10.1007/jhep10(2017)117 fatcat:dvkcbxnzfnebfdwyei3akvlry4
