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 ${\varphi }_2$; (2) Methods to extract ${\varphi }_3$ from $B\to K\pi$ decays; (3) Effects of non-minimal SUSY on B and K decays; (4) Understnding large branching ratios for $B\to {\eta }^{\prime }+K(K^{\ast })$ decays; (5) New calculation for hadronic matrix elements which are needed to compute ${ϵ}^{\prime }/ϵ$.
