How to tame penguins: Advancing to high-precision measurements of $ϕ_{d}$ and $ϕ_{s}$

Kristof De Bruyn, Robert Fleischer, Eleftheria Malami

The complex phases $ϕ_{d}$ and $ϕ_{s}$ , associated with the mixing between neutral $B_{q}^{0}$ and $B ˉ_{q}^{0}$ mesons ( $q \in {d, s}$ ), are key observables to test the Standard Model and s…

Taming Penguins: Towards High Precision Measurements in $ϕ_{d}$ and $ϕ_{s}$

Kristof De Bruyn, Robert Fleischer, Eleftheria Malami

Experimentally, the phases $ϕ_{d}$ and $ϕ_{s}$ are determined from CP asymmetry measurements in the "golden modes" $B_{d}^{0} \to J / ψ K_{S}^{0}$ and $B_{s}^{0} \to J / ψ ϕ$ . At leading order,…
