Summary of CKM 2023 working group 5: Direct CP violation (DCPV) including $ϕ_{3} / γ$ from $B \to D K$ , DCPV effects, branching fractions and polarisation in charmless $B_{(s)}$ decays

Melissa Cruz Torres, Tobias Huber, Minakshi Nayak +1

In this contribution a summary of the activities of Working Group 5 (WG5) presented during the 12th International Workshop on the CKM Unitarity Triangle (CKM2023) is reported. This…

Estimating QCD-factorization amplitudes through $S U (3)$ symmetry in $B \to P P$ decays

Tobias Huber, Gilberto Tetlalmatzi-Xolocotzi

We estimate the potential size of the weak annihilation amplitudes in QCD factorization as allowed by experimental data. To achieve this goal, we establish a connection between the…

Mapping out the Space for New Physics with Leptonic and Semileptonic $B_{(c)}$ Decays

Robert Fleischer, Ruben Jaarsma, Gilberto Tetlalmatzi-Xolocotzi

Decays of $B$ mesons with leptons in the final state offer an interesting laboratory to search for possible effects of physics from beyond the Standard Model. In view of puzzling p…

Probing Lepton Universality with (Semi)-Leptonic B decays

Giovanni Banelli, Robert Fleischer, Ruben Jaarsma +1

The most recent measurements of the observables $R_{D^{(*)}}$ are in tension with the Standard Model offering hints of New Physics in $b \to c ℓ ν ˉ_{ℓ}$ transitions…

Decoding (Pseudo)-Scalar Operators in Leptonic and Semileptonic $B$ Decays

Giovanni Banelli, Robert Fleischer, Ruben Jaarsma +1

We consider leptonic $B^{-} \to ℓ^{-} ν ˉ_{ℓ}$ and semileptonic $B ˉ \to π ℓ^{-} ν ˉ_{ℓ}$ , $B ˉ \to ρ ℓ^{-} ν ˉ_{ℓ}$ decays and present a strategy to determine short-d…

Rare top quark decays at a 100 TeV proton-proton collider: $t \to bW Z$ and $t \to h c$

Andreas Papaefstathiou, Gilberto Tetlalmatzi-Xolocotzi

We investigate extremely rare top quark decays at a future proton-proton collider with centre-of-mass energy of 100 TeV. We focus on two decay modes: radiative decay with a $Z$ bos…
