1. What R K and Q 5 can tell us about New Physics in b → sℓℓ transitions? / Algueró, Marcel ; Capdevila, Bernat ; Descotes-Genon, Sébastien ; Masjuan, Pere ; et al
The deviations with respect to the Standard Model that are currently observed in b → s ℓℓ transitions, or B anomalies, can be interpreted in terms of different New Physics (NP) scenarios within a model-independent effective approach. [...]

2. The CKM parameters in the SMEFT / Descotes-Genon, Sébastien ; Falkowski, Adam ; Fedele, Marco ; González-Alonso, Martín ; et al
The extraction of the Cabibbo-Kobayashi-Maskawa (CKM) matrix from flavour observables can be affected by physics beyond the Standard Model (SM). [...]

3. Are we overlooking lepton-flavor-universal new physics in bs ? / Algueró, Marcel ; Capdevila, Bernat ; Descotes-Genon, Sébastien ; Masjuan, Pere ; et al
The deviations with respect to the Standard Model that are currently observed in bs transitions (the so-called flavor anomalies) can be interpreted in terms of different new physics (NP) scenarios within a model-independent effective approach. [...]

4. Searching for New Physics with bsτ+τ Processes / Capdevila, Bernat ; Crivellin, Andreas ; Descotes-Genon, Sébastien ; Hofer, Lars ; et al
In recent years, intriguing hints for the violation of lepton flavor universality (LFU) have been accumulated in semileptonic B decays, both in the charged-current transitions bcν¯ (i.e., RD, RD*, and RJ/ψ) and the neutral-current transitions bs+ (i.e., RK and RK*). [...]

5. Patterns of New Physics in b → s ℓ + ℓ − transitions in the light of recent data / Capdevila, Bernat ; Crivellin, Andreas ; Descotes-Genon, Sébastien ; Matias, Joaquim ; et al
In the Standard Model (SM), the rare transitions where a bottom quark decays into a strange quark and a pair of light leptons exhibit a potential sensitivity to physics beyond the SM. [...]

6. Disentangling weak and strong interactions in B→K∗(→Kπ)π Dalitz-plot analyses / Charles, Jérôme ; Descotes-Genon, Sébastien ; Ocariz, José ; Pérez Pérez, Alejandro ; et al
Dalitz-plot analyses of B→Kππ decays provide direct access to decay amplitudes, and thereby weak and strong phases can be disentangled by resolving the interference patterns in phase space between intermediate resonant states. [...]

7. Hadronic uncertainties in B → K ∗ μ + μ − : a state-of-the-art analysis / Capdevila, Bernat ; Descotes-Genon, Sébastien ; Hofer, Lars ; Matias, Joaquim
In the absence of direct evidence for New Physics at present LHC energies, the focus is set on the anomalies and discrepancies recently observed in rare b → s ℓℓ transitions which can be interpreted as indirect hints. [...]

Left-Right (LR) models are extensions of the Standard Model where left-right symmetry is restored at high energies, and which are strongly constrained by kaon mixing described in the framework of the |Δ S | = 2 effective Hamiltonian. [...]
