Triangle Feynman diagram in the timelike region

Mikhail A. Ivanov, Dmitri Melikhov, Silvano Simula

In Quantum Field Theory, triangle Feynman diagram $F (p_{1}^{2}, p_{2}^{2}, p_{3}^{2} ∣ m_{1}, m_{2}, m_{3})$ is an analytic function of its variables, whose analytic structure is fully determined by the l…

A Dispersive Look at Rare $B$ -meson Semileptonic Decays

Marco Ciuchini, Marco Fedele, Ayan Paul +5

Rare semileptonic $b \to s$ flavour-changing neutral current transitions provide stringent tests of the Standard Model. Their interpretation is limited by hadronic uncertainties, n…

Inclusive $B ˉ_{s} \mapsto X_{s ˉ c} ℓ ν ˉ$ 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 $B ˉ_{s} \mapsto X_{s ˉ c} ℓ ν ˉ$ from first principles in lattice QCD. The physical decay rate is…

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_{\…

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

Matteo Di Carlo, Simone Bacchio, Erik Bäske +12

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