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…

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, $a_{μ}$ , updating the first White Paper (WP20) [1]. The pure QED and electroweak contrib…

Lattice QCD determination of the radiative decay rates $h_{c} \to η_{c} γ$ and $h_{b} \to η_{b} γ$

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

We present the results of our lattice QCD computation of the hadronic matrix elements relevant to the $h_{c} \to η_{c} γ$ and $h_{b} \to η_{b} γ$ decays by using the gauge configuratio…

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…
