Optimised observables and new physics prospects in the penguin-mediated decays B d(s) → K (∗)0 ϕ
Abstract We study the penguin-mediated B ¯ d s → K ¯ ∗ 0 K ∗ 0 ϕ $$ {\overline{B}}_{d(s)}\to {\overline{K}}^{\ast 0}\left({K}^{\ast 0}\right)\phi $$ transitions, proposing a new optimised observable L K*ϕ from the ratio of longitudinal branching ratios of these decays, with limited hadronic uncertai...
