Summary of Weak Decays, CKM and CP Violation Session Penguins

Abstract

In our subgroup, we focused on penguin physics from various different angles. Our discussions included: (1) A method to extract one of the angles of the unitarity triangle $ϕ_2$; (2) Methods to extract $ϕ_3$ from $B\to Kπ$ decays; (3) Effects of non-minimal SUSY on B and K decays; (4) Understnding large branching ratios for $B\to η'+K(K^*)$ decays; (5) New calculation for hadronic matrix elements which are needed to compute $ε'/ε$.
