Inclusive $B ˉ_{s} \mapsto X_{s ˉ c} ℓ I^ˉ ½$ decays from lattice QCD: computational strategy and a first physical result

Alessandro De Santis, Antonio Evangelista, Gael Finauri +16

We present a strategy to compute the inclusive decay rate for the process $B ˉ_{s} \mapsto X_{s ˉ c} ℓ I^ˉ ½$ from first principles in lattice QCD. The physical decay rate i…

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'^-…

Rare kaon decays $K^{-} \to ℓ^{-} I^ˉ ½_{ℓ} ℓ^{' +} ℓ^{' -}$ : 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, $K^{-} \to ℓ^{-} I^ˉ ½_{ℓ} ℓ^{' +} ℓ^{' -}$ ( $K_{ℓ 2 ℓ^{'}}$ ), are suppressed at order $O(G_{F}^{2}Î±_…

Charmonium radiative transitions to dileptons from lattice QCD: The case of $h_{c} \to I^\cdot_{c} ℓ^{+} ℓ^{-}$ and $I ¨ _{c 1} \to J / I ¨ ℓ^{+} ℓ^{-}$

D. BeÄireviÄ, R. Di Palma, R. Frezzotti +4

We present a lattice QCD study of dilepton production in charmonium transitions, specifically focusing on the $1^{+-} \to 0^{-+}$ and $1^{++} \to 1^{--}$ processes: $h_c \to Î·_c \…

First-principle evaluation of inclusive hadronic $I ¨ $ decays in QCD+QED

Matteo Di Carlo, Simone Bacchio, Erik BÃ¤ske +12

We present a strategy to extend lattice calculations of inclusive hadronic $I ¨ $ decays from isosymmetric QCD to QCD+QED. The inclusive decay rate can be related to suitable Euclide…

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…
