CP Violation in Multibody $B$ Decays from QCD Factorization

Rebecca Klein, Thomas Mannel, Javier Virto +1

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 $B^{-}\to {\pi }^{-}{\pi }^{+}{\pi }^{-}$. While some…
