Complete lattice QCD calculation of $K^{-} \to ℓ^{-} ν ˉ_{ℓ} ℓ^{^{'} +} ℓ^{^{'} -}$ form factors

R. Di Palma, R. Frezzotti, G. Gagliardi +6

We present the first complete lattice QCD calculation of the four structure-dependent form factors governing the rare charged kaon decay $K^{-} \to ℓ^{-} ν ˉ_{ℓ} ℓ^{' +} ℓ^{' -}$ …

Rare kaon decays $K^{-} \to ℓ^{-} ν ˉ_{ℓ} ℓ^{' +} ℓ^{' -}$ : Standard Model predictions from lattice QCD

R. Di Palma, R. Frezzotti, G. Gagliardi +6

Weak decays of charged kaons with an additional lepton-antilepton pair, $K^{-} \to ℓ^{-} ν ˉ_{ℓ} ℓ^{' +} ℓ^{' -}$ ( $K_{ℓ 2 ℓ^{'}}$ ), are suppressed at order $O(G_{F}^{2}α_{\…

Theoretical framework for lattice QCD computations of $B \to K ℓ^{+} ℓ^{-}$ and $B ˉ_{s} \to ℓ^{+} ℓ^{-} γ$ decays rates, including contributions from charming penguin diagrams

R. Frezzotti, G. Gagliardi, V. Lubicz +6

We develop a strategy for computing the $B \to K ℓ^{+} ℓ^{-}$ and $B ˉ_{s} \to γ ℓ^{+} ℓ^{-}$ decay amplitudes using lattice QCD (where $ℓ^{\pm}$ are charged leptons). We focus on…

Kaon radiative leptonic decay rates from lattice QCD simulations at the physical point

R. Di Palma, R. Frezzotti, G. Gagliardi +6

We present a lattice QCD calculation of the radiative leptonic decay rates of the kaon, improving upon our previous work, arXiv:2006.05358. Our analysis uses gauge ensembles genera…

Super-Leading Logarithms in $pp \to 2$ Jets

Thomas Becher, Patrick Hager, Giuliano Martinelli +3

Jet observables at hadron colliders feature ''super-leading'' logarithms, double-logarithmic corrections resulting from a breakdown of color coherence due to complex phases in hard…

What we can learn from the angular differential rates (only) in semileptonic $B \to D^{*} ℓ ν_{ℓ}$ decays

G. Martinelli, S. Simula, L. Vittorio

We present a simple approach to the study of semileptonic $B \to D^{*} ℓ ν_{ℓ}$ decays based on the angular distributions of the final state particles only. Our approach is model…

The $B_{s} \to μ^{+} μ^{-} γ$ decay rate at large $q^{2}$ from lattice QCD

R. Frezzotti, G. Gagliardi, V. Lubicz +5

We determine, by means of lattice QCD calculations, the local form factors describing the $B_{s} \to μ^{+} μ^{-} γ$ decay. For this analysis we make use of the gauge configurations pr…

We present an updated determination of the values of $∣ V_{c b} ∣$ , $R (D^{*})$ and $∣ V_{u b} ∣/∣ V_{c b} ∣$ based on the new data on semileptonic $B \to D^* \el…
