Lattice QCD investigation of the structure of the meson
Constantia Alexandrou, Joshua Berlin, Mattia Dalla Brida +3
We investigate the quark content of the scalar meson using lattice QCD. To this end we consider correlation functions of six different two- and four-quark interpolating…
Investigation of New Methods for Numerical Stochastic Perturbation Theory in Theory
Mattia Dalla Brida, Marco Garofalo, A. D. Kennedy
Numerical stochastic perturbation theory is a powerful tool for estimating high-order perturbative expansions in lattice field theory. The standard algorithms based on the Langevin…
SMD-based numerical stochastic perturbation theory
Mattia Dalla Brida, Martin Lüscher
The viability of a variant of numerical stochastic perturbation theory, where the Langevin equation is replaced by the SMD algorithm, is examined. In particular, the convergence of…
Investigating efficient methods for computing four-quark correlation functions
Abdou Abdel-Rehim, Constantia Alexandrou, Joshua Berlin +3
We discuss and compare the efficiency of various methods, combinations of point-to-all propagators, stochastic timeslice-to-all propagators, the one-end trick and sequential propag…
