Complete lattice QCD calculation of $K^{-} \to ℓ^{-} I^ˉ ½_{ℓ} ℓ^{^{'} +} ℓ^{^{'} -}$ 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 \ell^- \barÎ½_\ell \ell'^+ \ell'^-…

Theoretical framework for lattice QCD computations of $B \to K ℓ^{+} ℓ^{-}$ and $B ˉ_{s} \to ℓ^{+} ℓ^{-} I^^{3}$ 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 $B ˉ_{s} \to I^^{3} ℓ^{+} ℓ^{-}$ decay amplitudes using lattice QCD (where $ℓ^{\pm}$ are charged leptons). We focus on…

Inclusive hadronic decay rate of the $I ¨ $ lepton from lattice QCD: the $u ˉ s$ flavour channel and the Cabibbo angle

C. Alexandrou, S. Bacchio, A. De Santis +13

We present a lattice determination of the inclusive decay rate of the process $I ¨ \mapsto X_{u s} I^½_{I ¨} $ in which the $I ¨ $ lepton decays into a generic hadronic state $X_{u s}$ with $…
