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…

The anomalous magnetic moment of the muon in the Standard Model: an update

R. Aliberti, T. Aoyama, E. Balzani +232

We present the current Standard Model (SM) prediction for the muon anomalous magnetic moment, $a_{I^} ¼$ , updating the first White Paper (WP20) [1]. The pure QED and electroweak contri…

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…

Lattice QCD determination of the radiative decay rates $h_{c} \to I^\cdot_{c} I^^{3}$ and $h_{b} \to I^\cdot_{b} I^^{3}$

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

We present the results of our lattice QCD computation of the hadronic matrix elements relevant to the $h_{c} \to I^\cdot_{c} I^^{3}$ and $h_{b} \to I^\cdot_{b} I^^{3}$ decays by using the gauge configur…
