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,…

Studies of New Physics in $B_{q}^{0} - B ˉ_{q}^{0}$ Mixing and Implications for Leptonic Decays

Kristof De Bruyn, Robert Fleischer, Eleftheria Malami +1

The phenomenon of $B_{q}^{0}$ - $B ˉ_{q}^{0}$ mixing ( $q = d, s$ ) provides a sensitive probe for physics beyond the Standard Model. We have a careful look at the determination of the Unitar…

New Physics in $B_{q}^{0} - B ˉ_{q}^{0}$ Mixing: Present Challenges, Prospects, and Implications for $B_{q}^{0} \to μ^{+} μ^{-}$

Kristof De Bruyn, Robert Fleischer, Eleftheria Malami +1

The phenomenon of $B_{q}^{0} - B ˉ_{q}^{0}$ mixing ( $q = d, s$ ) provides a sensitive probe for physics beyond the Standard Model. We explore the corresponding space for New Physics left thro…

Penguin Effects in $B_{d}^{0} \to J / ψ K_{S}^{0}$ and $B_{s}^{0} \to J / ψ ϕ$

Marten Z. Barel, Kristof De Bruyn, Robert Fleischer +1

Controlling the contributions from doubly Cabibbo-suppressed penguin topologies in the decays $B_{d}^{0} \to J / ψ K_{S}^{0}$ and $B_{s}^{0} \to J / ψ ϕ$ is mandatory to reach the highest possible pre…
