Progress and challenges in the study of direct CP violation and $γ$ determinations: summary of CKM 2018 working group V

Abstract

Purely hadronic B decays are vital to the study of CP violation within and beyond the Standard Model of particle physics. One key contribution is the determination of of the CKM angle γ. In addition, very large direct CP violation has been observed in regions of phase space of multi-body hadronic decays, the description of which remains a significant challenge. In this summary, we discuss the recent results and progress for the determination of γ and direct CP violation in purely hadronic B decays as presented at CKM 2018.
