Real-time topological rate at non-zero momentum in quenched QCD

Claudio Bonanno, Massimo D'Elia, Roberto Dionisio +5

We present a proof-of-concept numerical study of the real-time topological rate at non-zero momentum in quenched lattice QCD at a temperature $T ≃ 1.24 T_{c} ≃ 360$ MeV,…

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…

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 \…

Lattice determination of the QCD low-energy constant $ℓ_{7}$

Claudio Bonanno, Gilberto Colangelo, Francesco D'Angelo +8

We provide a non-perturbative determination of the scheme- and scale-independent low-energy constant $ℓ_{7}$ , appearing in the QCD effective chiral Lagrangia…

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…

The smeared $R$ -ratio in isoQCD from first-principles lattice simulations

Francesca Margari, Simone Bacchio, Alessandro De Santis +6

The $R$ -ratio is a phenomenological observable of great relevance, both in itself and in applications such as the dispersive approach to the muon anomalous magnetic moment. It can…
