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 $T^$ within the Krylov subspace spanned by $\hat{T}^n…

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 $P$ -wave form factors contributing to $B_{s}$ to $D_{s}$ 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 $B_{s}$ meson to the $P$ -wave $D_{s}^{**}$ states from $B_{s}$ four-point correlators. With the…
