Rare FCNC radiative leptonic $B_{s, d} \to γ l^{+} l^{-}$ decays in the Standard Model

Anastasiia Kozachuk, Dmitri Melikhov, Nikolai Nikitin

We revisit rare radiative leptonic decays $B_{s, d} \to γ e^{+} e^{-}$ and $B_{s, d} \to γ μ^{+} μ^{-}$ in the Standard Model and provide the updated estimates for various differential distributio…

Rare FCNC radiative leptonic decays $B \to γ ℓ^{+} ℓ^{-}$

Dmitri Melikhov, Anastasiia Kozachuk, Nikolai Nikitin

We present our recent results for long-distance QCD effects in the FCNC radiative leptonic decays $B \to γ ℓ^{+} ℓ^{-}$ , $ℓ = {e, μ}$ . One encounters here two distinct types of lon…

Updated branching fraction measurements of $B_{(s)}^{0} \to K_{S}^{0} h^{+} h^{' -}$ decays

LHCb collaboration, R. Aaij, B. Adeva +776

The charmless three-body decays $B_{(s)}^{0} \to K_{S}^{0} h^{+} h^{' -}$ (where $h^{(')} = π, K$ ) are analysed using a sample of $pp$ collision dat…

Resonances and $C P$ violation in $B_{s}^{0}$ and $B_{s}^{0} \to J / ψ K^{+} K^{-}$ decays in the mass region above the $ϕ (1020)$

LHCb collaboration, R. Aaij, B. Adeva +770

The decays of $B_{s}^{0}$ and $B_{s}^{0}$ mesons into the $J / ψ K^{+} K^{-}$ final state are studied in the $K^{+} K^{-}$ mass region above the $ϕ (1020)$ meson in order to determine the res…
