Unbiased Krylov subspace method for the extraction of ground state from lattice correlators
Ryutaro Tsuji, Shoji Hashimoto, Ryan Kellermann
Ground-state energy and matrix element are reconstructed from correlators in lattice QCD by diagonalizing transfer matrix within the Krylov subspace spanned by $\hat{T}^n…
Study on the systematic effects on inclusive semileptonic decays
Alessandro Barone, Ahmed Elgaziari, Shoji Hashimoto +4
We discuss the calculation of the inclusive semileptonic decay for the process using lattice QCD. This calculation could be decisive in understanding the lo…
Inclusive semileptonic decays from lattice QCD: continuum and chiral extrapolation
Ryan Kellermann, Alessandro Barone, Ahmed Elgaziari +4
We present results for the inclusive semileptonic decay rate from lattice QCD. Chiral and continuum extrapolations are performed using gauge ensembles gene…
Inclusive and exclusive semileptonic decays of heavy mesons on the lattice
Zhi Hu, Alessandro Barone, Ahmed Elgaziari +4
We report the recent progress from our group in extracting observables of both inclusive and exclusive semileptonic heavy-meson decays directly from lattice QCD four-point correlat…
Inclusive semileptonic decays from lattice QCD: analysis of systematic effects
Ryan Kellermann, Alessandro Barone, Ahmed Elgaziari +4
Lattice QCD calculations of inclusive semileptonic decay rates involve new types of systematic effects, such as truncation errors in the estimation of energy integrals, or finite-v…
Study on the -wave form factors contributing to to inclusive semileptonic decays from lattice simulations
Zhi Hu, Alessandro. Barone, Ahmed Elgaziari +4
We present a pilot study on extracting the form factors of the semileptonic decay of a meson to the -wave states from four-point correlators. With the…
