Theoretical framework for lattice QCD computations of and decays rates, including contributions from charming penguin diagrams
R. Frezzotti, G. Gagliardi, V. Lubicz +6
We develop a strategy for computing the and decay amplitudes using lattice QCD (where are charged leptons). We focus on…
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 and
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 and decays by using the gauge configur…
Strange and charm quark contributions to the muon anomalous magnetic moment in lattice QCD with twisted-mass fermions
C. Alexandrou, S. Bacchio, A. De Santis +15
We present a lattice calculation of the Hadronic Vacuum Polarization (HVP) contribution of the strange and charm quarks to the anomalous magnetic moment of the muon in isospin symm…
Lattice QCD determination of the normalization of the leading-twist photon distribution amplitude and susceptibility of the quark condensate
S. Bacchio, D. BeÄireviÄ, G. Gagliardi +1
The normalization of the leading-twist photon distribution amplitude (DA), $f_γ^{\perp}$, is an important ingredient in the study of exclusive processes involving the photon emiss…
