Analytic decomposition of two-body electroweak processes with left-hand cuts

AndrÃ© BaiÃ£o-Raposo, RaÃºl A. BriceÃ±o, Nicolas Lang +2

We derive an on-shell representation for electroweak $2 + J \to 2$ transition amplitudes involving two hadrons in both the initial and final state for systems where there are left-hand…

$D_{1}$ and $D_{2}$ resonances in coupled-channel scattering amplitudes from lattice QCD

Nicolas Lang, David J. Wilson

Isospin-1/2 charmed axial-vector $D^{*} I ¨ - D^{*} I^\cdot - D_{s}^{*} K ˉ$ scattering amplitudes are computed, along with interactions in several other $I = 1/2$ $J^{P}$ channels. Using lattice QCD,…

Optimising stochastic algorithms for hadron correlation function computations in lattice QCD using a localised distillation basis

Nicolas Lang, Robert G. Edwards, Michael J. Peardon

Distillation is a quark-smearing method for the construction of a broad class of hadron operators useful in lattice QCD computations and defined via a projection operator into a ve…
